Re: Ignite node log file setup

[akorensh]

Hi,
   Update the file appender, and put cache-node-01 into the filename 
property as below.

   
   


Use env variables in your appenders, or re-config at run time as need
be.
 see: https://apacheignite.readme.io/docs/logging#log4j2

   You can also pro-grammatically create the log4j/logj2 config before
starting a grid, and put the grid name into the fileName property.

Thanks, Alex

Re: How to get POJOs in Python?

[Andrew Munn]

I have only a few classes but they have a large number of fields.   I will
think about some code generation for Python.

 Thanks Ilya.  I don't see anything in that post about registering the
 binary type.  I am not defining any tables using SQL.  I'm just
 instantiating POJOs, putting them in the cache and then expecting to get
 them in Python.  Can you tell me what else is required?  Is there some
 process to register the binary type?  How can I view all registered binary
 types?

 Thanks!

BinaryObjectException: Conflicting enum values

[Andrew Munn]

I'm seeing the same issue as this one

.

I had values in the cache.  I cleared the cache, but did not shutdown the
cluster node.  I modified the enums in the class.  Then I repopulated the
cache with instances of the updated class.  There must be some way to purge
leftover metadata without bringing the cluster down, right?   Can it be
purged when the cache is cleared?

Thanks

Hello!

I think that people usually have few enough classes so they can define them

Re: How to get POJOs in Python?

[Andrew Munn]

That's very helpful.  Thanks.  So it appears if I want to put in an object
using Java and consume it using Python I have to define the matching class
as done in that example.

Do you know how this is being used in practice?  Are people generally
kicking off a build job that looks at Java classes and performs code
generation to output Python version that get included in libs?

 I would like to put POJOs in a map and get them using pyignite.  Python
 gives me ParseError('Binary type is not registered'). I was hoping
 that Ignite would automatically store any required schema info for the
 class so Python could use it. Especially if my simple POJO was composed
 only of primitives.

 Are there any examples of consuming POJOs from a cache using Python?

 Thanks

Re: UriDeployment Exception

[marble.zh...@coinflex.com]

Finally get works for this approach, it due to my maven package issue, thanks
a lot.

1. copy the dependency libs to ignite ./libs;
2. copy the package classes into the urideployment folder.

No need the ignite.xml, and no need to restart the server, it will use the
latest code. 

thanks again.

Ignite SqlFieldQuery Unicode Characters Support

[Ravi Makwana]

Hi,

We are using Apache ignite version 2.7 and we have one node cluster with
150 caches out of 150 We have 1 cache which contains Unicode characters
like Chinese language.

Server node is running on Linux OS & Client node is running on Windows OS.

Client side we are using sqlquery & sqlfieldquery to fetch and put &
data-streamer to insert data using .net ignite apis.

In ignite cache,we have AddressFull property which contains Unicode
characters like Chinese language so while inserting we have inserted
specified data into AddressFull property which is mentioned below.

*"北京市朝阳区安贞西里四区甲1号, 北京, 中国, 100011"*

While fetching data from ignite cache we have observed that we are not
getting inserted data properly.

We have performed below mentioned sqlquery using SqlFieldQuery.

SELECT HotelCode,AddressFull FROM HotelOtherLanguageMasterModel WHERE
HotelCode = '12345'

We got below mentioned result data for AddressFull property.

*"北京市�阳区安贞西里四区甲1�, 北京, 中国, 100011"*

Based on this test we have couple of questions on the same.

1) Is SqlFieldQuery .net api supporting Unicode characters?
2) If Yes, How do we overcome this issue?

Regards,
Ravi Makwana

Ignite node log file setup

[kay]

Hello, I set up log4j2.xml and I found a create log file with sys:nodeId.

I configured grid name like 

cache-node-01, cache-node-02 using xml confiuration(property
name="igniteInstanceName" value="cache-node-01")

Is there any way to setup log file with grid name.

for example) ignite-cache-node-01.log

Thank you so much
