Currently the DataContext is used as a holder for data fetched from
Cassandra and so the serializing of DataContext is not trivial and not very
useful as well.

IIUC, I believe it would be more appropriate if it is possible to make the

+1. This decouples run time data and configuration data currently present
in the DataContext. We can basically use DataContext for holding run time
data (basically fetched data) which would be specific for the particular
execution of the task.

Re: [Dev] Running some code when installing a feature for C4

[Buddhika Chamith]

Yes if we have some thing like this at the moment we may be able to
leverage it for our tool box stuff as well. Refer thread on "Deployment of
Domain Specific ToolBoxes for BAM" on architecture list.

 Hi,

 yes, it should be possible. The rationale is,

 when installing features, we already do things such as file-copying,
 extracting, etc. Those are implemented as eclipse touchpoint actions. We
 can come up with our own touchpoint implementations.

 within the framework hook of the touchpoint implementation, we should
 be able to do whatever we want. :)

 then again, why we want this ? can you please explain the scenario.

Re: [Dev] [platform] why several libthrift orbit versions?

Yes having the same version may not be practical since specially due to
Cassandra dependency on an earlier version of Thrift which is AFAIK is
incompatible with new version. Identity and Agent components use new
features present in Thrift if I am not mistaken which are not present in
the version used by Cassandra. Not sure about dss though.

[Dev] Enabling equinox trace logs in trunk carbon

[Buddhika Chamith]

Hi All,

I see that osgi-debug.options file not included the distribution anymore
even though the launch.ini still refer to this file in it's old location
(./lib/core/WEB-INF/eclipse - commented out by default). I think its useful
to have this option since it's helpful to debug some situations where the
carbon server hangs without any error logs.

Re: [Dev] Build failure in Orbit

[Buddhika Chamith]

I have forked datanucleus under dependencies since it was required to be
patched for hive stuff. You are right in that it should come under
dependencies/orbit to where I have moved it now. Need to look in to test
failures coming from datanucleus. However for the moment can you continue
without building without tests of datanucleus.

Both hadoop and datanucleus has been moved to
platform/trunk/dependencies/orbits from orbit/trunk yesterday. Possibly
orbits and platform build checkouts happened in an intermediate state?

Re: [Dev] Hadoop download in platform/trunk/dependencies/hive clog the build

[Buddhika Chamith]

Hi,

It will not download these distributions on subsequent builds since it
caches them. I think it is using these different hadoop versions to run
compatibility tests with those hadoop versions. However I will look in to
whether we can make this picked from nexus.

Buddhika

Re: [Dev] Compilation errors from Apache-Hive dependency

[Buddhika Chamith]

This happens due to build target folder not being cleaned up properly so
will not happen for first time builders. I have added a clean target now so
it should be fine now.

[Dev] BAM2 Milestone 3 Released

[Buddhika Chamith]

WSO2 is pleased to announce availability of BAM2 Milestone 3. This
milestone cannot be tested for samples or end-end scenarios because of
Ongoing/Removed features. Testing will be possible in future milestones,
and will be announced as appropriate.

New features included in this release are

- Integration of SQL based HiveQL as the analytics language and Apache Hive
integration
- Apache Hive and Cassandra integration facilitating data retrieval from
Cassandra to Hive analytic jobs

Ongoing features
- Revamping Java SDK for Agent API
- Strongly typed events
- Gadget Generation wizard
- Data writing into Cassandra/ JDBC after running Hive jobs

Removed Features
- Adding analytics based on BAM Analyzer XML language
- Analyzer Framework

Hive analytic jobs can be programatically submitted using Hive JDBC driver
[1]. Samples on retrieving data from Cassandra to Hive can be found at [2].
Please note that these features are still work in progress and associated
user interfaces are currently being worked on and would be available in
next milestone releases.

Distribution can be downloaded from [3].

Re: [Dev] Hive build failure in windows

[Buddhika Chamith]

Hi,

I have removed the symlinks from the ant build since it's not required for
building maven artifacts. Would be great if some one running on windows can
verify whether it's building properly now.

 Hi Tharindu,

 Well, there is a slight relevance, and hence this e-mail. Take the
 service UI for example. Multiple products publish multiple kinds of
 services which have different semantics, but utilize a single UI. And,
 another example is a situation as in G-Reg. There can be multiple types of
 tasks that may get scheduled even in a single product. I'm not suggesting a
 100% generic UI, but I'm trying to understand the best solution to this
 situation. While we can write our own thing is an easy answer. How can I
 manage, understand and correlate all my tasks is definitely going to be a
 question to a user in the long run.

 Thanks,
 Senaka.

Re: [Dev] Massive amounts of Time spent on Building Dependencies with Ant-based Build Systems

Hi,

Sorry for the late reply. +1 for hosting the orbit. Hopefully there would
be infrequent changes to Hive code. I had to do several modifications to
Hive source to make it work inside Carbon and fix its Hadoop job submission
for BAM2 requirements.

[Dev] Adding a Data Source using DataSourceInformationRepositoryService OSGi service

[Buddhika Chamith]

Hi,

I tried $subject. Although I was able to add a DataSource the data source
definition doesn't seem to get persisted so that it won't survive across
server restarts and the added DataSource doesn't get listed in the
Datasources page as well. Going through the data-source component code I
see that there is additional logic to persist the definition to the
registry in the datasource admin service eventhough it's not included in
the OSGi service. I feel it would be beneficial the provide a comparable
set of functionalities across the web service and the OSGi service exposed.
Any ideas on this?

Buddhika

Yes. I was able to add datasource definition using the returned
DataSourceRepository. Would be great if this can be incorporated to the
coming release.

Yes. Event publishing happen via a queue in an async manner.

Re: [Dev] Stratos Usage and Summarizer to be migrated to use BAM2.

[Buddhika Chamith]

GroupBy analyzer followed by aggregate analyzer can be used to this
requirement. In the group by use time based grouping with required
granularity "DAY, MONTH, YEAR" etc.

 

 


 See [1]. These kind of aggregations would become much easy with Hive based
analytics in the future.

Buddhika

[Dev] Behavior of Entitlement mediator when authorization fails

[Buddhika Chamith]

Hi,

 I didn't see any log or exception at ESB when I tried the xacml sample
with a failed authorization. I was under the impression the flow would go
through the fault sequence once authorization failed. May I know the
intended behavior once this happens specially as seen by the client? (I am
simply getting an org.apache.axis2.AxisFault: The input stream for an
incoming message is null at my sample client. Shouldn't the error be more
specific for a failed authorization?).

Re: [Dev] Behavior of Entitlement mediator when authorization fails

[Buddhika Chamith]

Hi Suresh,

Well it's the entitlement mediator I tried out. I think you have tried out
the OAuth mediator. Anyway I am getting following log at IS.

[2012-06-17 08:31:45,595]  INFO
{org.wso2.carbon.identity.entitlement.policy.PolicyCollection} -  Matching
XACML policy found urn:sample:xacml:2.0:samplepolicy
[2012-06-17 08:31:45,599]  INFO
{org.wso2.carbon.identity.entitlement.pip.CarbonAttributeFinder} -  No
attribute designators defined for the attribute group

Did the flow went through the fault sequence when the OAuth authorization
failed?

Thanks and Regards
Buddhika

Re: [Dev] BAM201 exception when executing the default hive script, service_stats_306

[Buddhika Chamith]

Are you running BAM with an offset? If so to connect to embedded Cassandra
within the script you will need to change the default port specified in
Hive CREATE TABLE for Cassandra column family in the Hive script.

Please ignore. This was a case of 4.0.2 stub being not correctly built in
my build. Now working fine.

Re: [Dev] Can't install BAM Data Agents on top of AS 5.0.2

[Buddhika Chamith]

There is no much point in installing BAM mediator feature on top of AS
since this is specific for ESB. Having said that the issue is some thing
that needs to be fixed if possible.

Re: [Dev] An exception when publishing API manager events to BAM

[Buddhika Chamith]

This usually happens when an event not conforming to the stream definition
registered is sent. May be there has been some change to stream definition
in the toolbox or at agent side in versions being used?

[Dev] Doc on Roles and Permissions Configuration

[Buddhika Chamith]

Is there any doc on how to introduce fine grained permissions to the
permission tree with our components? I realize that there are certain
entries that can be provided in component.xml. I think we need it
documented some where properly if already not. So far couldn't find any
documentation on that. I think there are bunch of such entries we put in
component.xml which require to be documented properly.

Can you check the same with BAM 2.0.1? I suspect this might be a regression

We have decided not to release separate toolboxes for other databases with
this BAM release since there were concerns on maintainability of a such an
approach. This was discussed on a separate thread on dev list and we are
planning to have that discussed approach incorporated to next release so
that one toolbox can handle all the supported databases.

zookeeper duplication is already fixed and will be available with the next

Yes if it is the case then that's some thing which needs to be looked at.
After deleting scheduled tasks I believe the tasks were rescheduled right?
Were there any errors while re-scheduling the tasks?

Re: [Dev] SSO enabling BAM dashboard

[Buddhika Chamith]

Hi Pradeep,

We don't use SSO with our dashboard Jaggery app at the moment. User needs
to log in to the BAM dashboard separately. There was some difficulty in
sharing sessions between the management console and Jaggery applications at
the time BAM dashboard was being done IIRC. Chamath would be able to fill
in the specific details on that. Anyway I guess now we might be able to
rethink this with above mentioned approach if it solves our problem.

Regards
Buddhika

Re: [Dev] Behavior of Entitlement mediator when authorization fails

[Buddhika Chamith]

Hi,

I was able to return a SOAP fault to the client by explicitly specifying a
fault sequence (was under the impression if a fault sequence is not
specified it would go through the default fault sequence on an error
condition) containing a makeFault mediator for the proxy in order to return
the client the proper error. Otherwise it silently drops the message.
Thanks Asela for the off-line tip.

Buddhika

[Dev] Using DBReport mediator with a stored procedure

[Buddhika Chamith]

Hi,

Is it possible to use DBReport mediator to call a stored procedure having
both IN and OUT parameters? So basically we want to get some return value
from the procedure by invoking it with a set of parameters.

[Dev] BAM2 M5 Demo Session Notes

[Buddhika Chamith]

Rename KPI sample to Retail store sample.
Make figures for each item in the sample varied. (looks bad in the graphs
currently with all having same values)
Make some gadgets based on time.(requests per each hour etc.)


Look in to feature repo based tool box distribution and get tool boxes list
down from a p2 repo
  - Local p2 repo
  - From remote repo
Tool boxes can be released separately on continuous basis separate from BAM
major release.
Should have another name for tool box


Several UI issues need to be fixed.
  - Fix "Awaiting to deploy" text
  - Wrap text in the Hive editor


We need to call M5 as Alpha as it is feature complete?
Rename org.apache.hadoop.hive.jdbc to org.wso2.hadoop.hive.jdbc
Rename org.apache.hadoop.hive.cassandra to org.wso2.hadoop.hive.cassandra
Use secure vault for credentials provided in scripts.


Is database Hive JDBC handler writes to multi-tenanted? We can leverage
data sources to make this tenant aware.
Add support for JNDI, Carbon data sources for STORED BY clause in Hive
create table.


Event stream name in the api doesn't look good.
Need to review the REST API.
Take JAX-RS support discussion seperately (go through web app or carbon
component based support)


Make the BAM mediator consistent with the log mediator. Give options to
dump whole message body, part of it (xpath) or no message body at all with
only sending the headers.
Need a new name for BAM mediator now that this will push data for BAM and
CEP as well? Syntax should be consistent with log mediator syntax.
Published data should  include httpd style log lines, transport headers etc.


Have gadget server inside BAM. Use gadget repo with BAM specific gadgets.
Need to lose the dashboard.
Have a useful tool box (need to have better name for this) sample. Retail
store example plus some thing like log analytics with a sample log data
set? Process OT logs with BAM2.


For statistics BAM1 level stats monitoring is required.
Make the dashboard story work with Jasper Reports for mediation and service
statistics (need tps figures too).
Its ok to include Jasper war files inside bar file.
For the Jasper visualization story there couple of options. Need to
investigate and adopt the suitable option.
 - Make the whole dashboard with Jasper stuff
 - Make gadgets refer to Jasper UI elements within iframes

Please add anything I have missed.

Re: [Dev] Logging Implementation {was: Re: Any Possibility of defining the Hive output directory programmatically?}

[Buddhika Chamith]

Hi All,

It is not that it is impossible to inject runtime variables (bit like query
parameters in DSS) to Hive query execution it might take some modifications
from the hive side to make it possible in order to do it programatically.
Currently I am doing some work in Hive for making it tenant aware. What I
mentioned was that I can look to this as a part of that effort though it
might take couple of days time since I have to figure out a clean way to
expose tenant specific Hive Configuration to the carbon environment. Anyway
I was not aware of the thread on Hive user list and now going through that
I see that they have suggested an alternative way provided that we are ok
with modifying the original script.

Regards
Buddhika

Re: [Dev] Logging Implementation {was: Re: Any Possibility of defining the Hive output directory programmatically?}

[Buddhika Chamith]

So if I understand right the data are stored in seperate column families
per each tenant,server,day and the requirement is to transfer these column
family data directly to a flat file which corresponds to a logs from a
tenant for a server in a given day with no analytics involved. If it is the
case may I suggest using what tharindu suggested (insert select * from foo)
in combination with [1] in a loop for each column family. In order to
dynamically  provide the directory name and the column family name we can
use SET hive command and append it to the script before passing in to the
Hive execution service as also suggested at [2].

 They also mentioned that this approach is not possible.
 Also as per the chat I had with Buddhika, right now, these kind of
 dynamic variable creations is not possible in Hive that comes with 
 BAM2.

 Therefore IMO, without going ahead with this cumbersome process,
 the best way will be to run a scheduled java task to pick data from
 relevant Cassandra Column families and dynamically generate the 
 relevant
 log files (according to the tenantID and current date) which will be 
 stored
 in Apache Directory.

 As per the offline chat had with Azeez, will start to work on a
 custom Java task that can handle the above scenario.

correct me if I am wrong.

If there isn't an issue preventing that we can do the following.

Assume below is your hive query which transfers data from cassandra to
local file system.

DROP TABLE cassandraTable;
CREATE TABLE cassandraTable (tenantId INT,
serverName STRING,serviceName
STRING,date TIMESTAMP, logString STRING) STORED BY
'org.apache.hadoop.hive.cassandra.CassandraStorageHandler' WITH
SERDEPROPERTIES ( "cassandra.host" =
"127.0.0.1",
"cassandra.port" = "9160","cassandra.ks.name" = "EVENT_KS",
"cassandra.ks.username"
= "admin","cassandra.ks.password" = "admin",
"cassandra.cf.name" =
"${hiveconf:cfname}",
"cassandra.columns.mapping" =
":key,serverName,
payload_user,serviceName,date,logString" );
INSERT OVERWRITE LOCAL DIRECTORY {hiveconf:dir} select * from
cassandraTable;

Now say we have following cf log tables.

log_0_esbserver_2012_07_23
log_1_esbserver_2012_07_23
log_2_esbserver_2012_07_23

Now within the logging component we can do the following. (in pseudo-code)

for (each tenant i)
  for (each server j)
var logCf := log + _ + i + _ + server + _ + cur_date()
var logLocation := file:///../i/server/cur_date() // May need to create
folders if not existing at this point

var hiveScript := getScriptFromRegistry()
var setCfName := "SET cfname=" + logCf // set cf name variable
var hiveScript := setCfName + hiveScript // append it to the script

hiveScript.replace( "{hiveconf:dir}", logLocation) // Need to do a
regex replace since it is not possible to use variable substitution for
entity

// names such as directories/ tables etc.
HiveExecutionService.execute(hiveScript) // Execute the runtime
modified Hive script using Hive script execution OSGi service

There will be chances of parallelizing this script execution once we get
this basic form working. HTH.

Buddhika

Data-bridge features are required for service agent feature functionality.
So you will need to include these features as well.

[Dev] Getting Tenant Domain via CarbonContext APIs

[Buddhika Chamith]

I am seeing the following behavior when fetching tenant domain from
CarbonContext APIs.

CarbonContextHolder.getCurrentCarbonContextHolder().getTenantDomain()
returns NULL.
CarbonContext.getCurrentContext().getTenantDomain() returns NULL.
SuperTenantCarbonContext.getCurrentContext().getTenantDomain() returns NULL.

But getTenantId() is always successful returning -1234. Now if I try below
it gives super tenant domain.

SuperTenantCarbonContext.getCurrentContext().getTenantDomain(true) returns
the super tenant domain.

Afterwards above three methods will also return the super tenant domain
properly. So does this mean we have to use the variant accepting the
boolean (boolean resolve) always to be sure that the domain gets resolved
properly? Any best practices regarding the CarbonContext API usage would be
helpful in this regard. I am invoking these methods during component
initialization. IIRC it used to be the case that component initialization
codes did not run as any tenant in previous carbon version. I assume this
is not the case anymore with recent Tomcat OSGification changes?

Re: [Dev] 2 Versions of Antlr in the Platform and Product Binaries

Hi,

I had to add a new version (r125163) (a lower version) since Hive was
having troubles working with the latest antlr version during query
compilation. I will try to have another look at it and possibly move to the
newer version of antlr if possible.

Re: [Dev] Startup error when restarting carbon 4.0.1 after installing BAM feature category

[Buddhika Chamith]

Currently this db is created at BAM distribution creation time. Ideally
this should be created at runtime if the db has not been created already
which would require some changes in RSS component. However I was able to
succefully startup BAM server after copying this h2 db to
repository/databases location. So currently that can be used as a
workaround. Jira at [1].

[Dev] Merging BAM Activity Service and Mediator stream definitions

[Buddhika Chamith]

Currently we are having a single stream definition for service data agent
for including both service statistics and activity information. However for
activity mediator (BAM mediator) agent a different stream definition is
used since it's different in that no statistics information is present.
However this makes things bit difficult and less performant to correlate a
message flow between an App server and ESB since it would require join to
get data from two data column families. Analysis would become easier if
both activity service and mediation are to be published in to a single
stream.

A possible solution might be to separate out publishing of statistics data
and activity data in service agent in to two streams (this means two events
need to be published as well instead of one) and also having a separate
stream definition for baseline attributes (another stream def would be
required in the case of publishing custom attributes) of BAM mediator
publisher. This would require changes to both service and mediation
publisher to accommodate publishing to separate streams and make things bit
complex IMO since there would be couple of additional stream definitions in
certain cases. We might also have to think about the performance cost of
publishing two events instead of one.

Another option might be to use the current stream definition of activity
service agent to activity mediator agent so that all the data for activity
service, service statistics and activity mediation would be published to a
single column family. In this case we can just use Hive to have different
views of the same column family for different types of analytics (e.g:
analytics required for service stats, activity etc). Downside of this
approach is since all the data is that a single column family is now loaded
more.

We were thinking on going along with the first approach after some
discussion. Kasun please add anything else I have missed. Please shout if
there are any concerns and suggestions.

Re: [Dev] 4.0.3 build break - logging summarizer

[Buddhika Chamith]

poms for these jars are generated and installed to the repo during the hive
dependency build since they are not present by default in Hive sources. If
we can exclude transitive dependency check it should be ok I think.

Yes. It could be done by uncommenting required dashboard elements in
dashboard.xml found under
