Re: [jira] [Created] (ZEPPELIN-4937) mmlspark for lightgbm loading from zeppelin seems not working

[Khalid Huseynov]

In order to use mmlspark in pyspark you need to set PYSPARK_DRIVER_PYTHON
property (either in interpreter settings of spark interpreter or
zeppelin-en.sh) to point to the python path where your mmlspark is
installed. This way you can access mmlspark in your driver, if you need to
access it in executors as well then you need to set PYSPARK_PYTHON and make
sure your python environment is deployed to every worker node. Hope this
helps.

[jira] [Created] (ZEPPELIN-3639) Add Ipython interpreter prerequisite check for protobuf

 Summary: Add Ipython interpreter prerequisite check for protobuf
 Key: ZEPPELIN-3639
 URL: https://issues.apache.org/jira/browse/ZEPPELIN-3639
 Project: Zeppelin
  Issue Type: Improvement
  Components: Interpreters, python-interpreter
Affects Versions: 0.8.0, 0.9.0
Reporter: Khalid Huseynov


after grpcio 1.12 release [https://github.com/grpc/grpc/releases/tag/v1.12.0] 
it doesn't depend on protobuf, however we need protobuf to communicate with 
ipython kernel. thus we need to add prerequisite check for protobuf when 
starting ipython kernel

Re: [DISCUSS] Release 0.8.0

[Khalid Huseynov]

Thanks for starting discussion on 0.8.0 release. I also think that need to
concentrate on solving the issues blocking release and link the issues
community considers important for it under the umbrella issue you
mentioned.

Further regarding stable and latest release, here's one example how it
looks like in redis for instance https://redis.io/download

Re: Google OAuth in Zeppelin

[Khalid Huseynov]

Actually simple implementation for OpenId was done in
https://github.com/apache/zeppelin/pull/2373 through shiro using buji-pac4j
library as you said. This library provides integration realm for OAuth as
well, so I think good starting point would be to configure buji-pac4j with
OAuth realm, and theoretically it should be working or may need some
modifications to already existing flow.

Thanks for the questions guys!

@Jun Kim actually that feature was originally discussed and was put into
backlog since proposal was more about tables processed by interpreters and
their sharing. However having quick visualisation on the fly for not so
large data makes sense indeed, and possibly could be done by importing data
into some interpreter by default (Spark, python, etc). So I believe it can
be done once initial basics for resource sharing is completed.

@Andrea Santurbano there should be listing of tables with schema info, but
i'm not sure exactly what you mean by drop-down feature between tables in
the UI. Could you give little more details/example on that as well as
 enhancements on graph part you meant?

[jira] [Created] (ZEPPELIN-2593) Save to secondary storage only on checkpoint/commit

[Khalid Huseynov (JIRA)]

 Summary: Save to secondary storage only on checkpoint/commit
 Key: ZEPPELIN-2593

 Project: Zeppelin
  Issue Type: Improvement
Reporter: Khalid Huseynov
Assignee: Khalid Huseynov


Currently if having two notebook storage backends, notebook would be saved to 
both of them everytime save is initiated (e.g. run, modify, chart change). In 
case of in case of too many saves and corresponding network delays, it may 
cause some performance degradation. It would be useful to have an option 
(environment/UI) to perform save to secondary storage only when 
checkpointing/committing note on first storage.

When trying to commit the revision in version control menu, it show's tooltip 
on 'Commit' button however due to container sizes it doesn't appear properly. 
One  easy solution would be to delete the tooltip and keep menu style same. 
Also it would make it more consistent, since other parts of UI don't have 
tooltips inside of menu. Other ideas are welcome

In some cases, depending where authentication server is deployed and what 
services are used, it's possible that httpcomponents client request headers are 
not approved by the security rules. For example one of common problems can be 
403 Forbidden response by cloudflare service with error-code 1010.

In Zeppelin it's possible to separate user workspaces, however it's not well

 However it should be separated with own topic and more description. more

[jira] [Created] (ZEPPELIN-1745) Offline or non-editable view of notes when viewing revisions and as a feature itself

 Summary: Offline or non-editable view of notes when viewing 
revisions and as a feature itself
 Key: ZEPPELIN-1745
 URL: https://issues.apache.org/jira/browse/ZEPPELIN-1745
 Project: Zeppelin
  Issue Type: Improvement
Reporter: Khalid Huseynov
Assignee: Khalid Huseynov
 Fix For: 0.7.0


Currently when viewing different note revisions, it's still possible to edit 
the notes (e.g. ZEPPELIN-1190). First of all, notes should be view-only when 
viewing revisions. Secondly, note broadcasts shouldn't affect that mode, say 
`offline` mode.

When checkpointing note to make a revision, it's possible that corresponding 
backend storage system either doesn't support or failed to make a revision of 
note. In this case currently there's no way to know about it.

Re: 0.7 Shiro LDAP authentication changes? Unable to instantiate class [org.apache.zeppelin.server.LdapGroupRealm]

[Khalid Huseynov]

I think during refactoring LdapGroupRealm has moved into different package,
so could you try in your shiro config with:

ldapRealm = org.apache.zeppelin.realm.LdapGroupRealm

[jira] [Created] (ZEPPELIN-1657) Provide a way for user to create/import notes in private mode

 Summary: Provide a way for user to create/import notes in private 
mode
 Key: ZEPPELIN-1657
 URL: https://issues.apache.org/jira/browse/ZEPPELIN-1657
 Project: Zeppelin
  Issue Type: Improvement
Reporter: Khalid Huseynov


For having per user note workbench, there're should be an option for notes to 
be listed only in the user's list, for privacy issues. Thus there should be a 
way to pass this private/public note creation flag through the configurations.

after https://github.com/apache/zeppelin/pull/1330 is merged, users will be 
able to receive their own list of notes, however that list is currently loaded 
automatically only once when starting Zeppelin (also possible by clicking 
reload notes).

Thus, we need to address updating other users list of notes (workbench) on the 
fly when some note permissions are changed. For example if user1 gave read 
permissions to noteA for user2, noteA should appear immediately in user2's 
working directory of notes.

Although storage layer is aware of user (subject), the sync mechanism was 
unaware of it so far. So we need to propagate subject there as well.

[jira] [Created] (ZEPPELIN-1312) Inconsistency in getNotebookRevision method

[Khalid Huseynov (JIRA)]

Khalid Huseynov created ZEPPELIN-1312:
-

 Summary: Inconsistency in getNotebookRevision method
 Key: ZEPPELIN-1312
 URL: https://issues.apache.org/jira/browse/ZEPPELIN-1312
 Project: Zeppelin
  Issue Type: Bug
Reporter: Khalid Huseynov


[here|https://github.com/apache/zeppelin/blob/master/zeppelin-web/src/components/websocketEvents/websocketMsg.service.js#L173]
 frontend sends revisionId, however on backend 
[here|https://github.com/apache/zeppelin/blob/master/zeppelin-server/src/main/java/org/apache/zeppelin/socket/NotebookServer.java#L1204]
 revision is extracted. Thus it should be consistent.

[jira] [Created] (ZEPPELIN-1257) Get note revision api gets input parameter revision object instead of revisionId string

[Khalid Huseynov (JIRA)]

Khalid Huseynov created ZEPPELIN-1257:
-

 Summary: Get note revision api gets input parameter revision 
object instead of revisionId string
 Key: ZEPPELIN-1257
 URL: https://issues.apache.org/jira/browse/ZEPPELIN-1257
 Project: Zeppelin
  Issue Type: Sub-task
Reporter: Khalid Huseynov
Assignee: Khalid Huseynov
 Fix For: 0.7.0


When getting certain revision of note in the storage layer, currently it's 
expected to get the whole Revision object. However the whole object is 
unnecessary and only unique revisionId is required.

Re: integrate authorization

[Khalid Huseynov]

Yes, I believe main point of #1173
 is to have authentication
using remote web server. It can be basically generalized to support what
you're talking about. You may review that PR as well for more details.

Re: Notebook copy per session/socket

[Khalid Huseynov]

Thanks for the question Ashish,

Actually it's a good feedback, and one of the reasons
https://github.com/apache/zeppelin/pull/1105 was proposed is to facilitate
the case of using note as a dashboard without intervening with storage and
other notebooks. I'll consider this feedback in the PR then and possibly
you can go ahead and try it and leave more feedback there.

Best,
Khalid.

This is basically version control flow for the notebooks. It would be useful to 
be able to list the history of notebook revisions, view them, and restore 
notebook to some of previous revisions.
