Resolution: Fixed
> Issue with zeppelin after upgrade
> ---------------------------------
>
> Key: AMBARI-23234
> URL: https://issues.apache.org/jira/browse/AMBARI-23234
> Project: Ambari
> Issue Type: Bug
> Components: ambari-server
> Affects Versions: 2.6.1
> Reporter: Dmitry Lysnichenko
> Assignee: Dmitry Lysnichenko
> Priority: Blocker
> Labels: pull-request-available
> Fix For: 2.6.2
>
> Time Spent: 2h 10m
> Remaining Estimate: 0h
>
> I performed the express upgrade to latest fenton build which has the fix for
> AMBARI-23113
> Observed below issues after upgrading cluster from ambari-2.5.1.0 with
> 2.6.1.0-129 to ambari-2.6.2.0-96+HDP-2.6.5.0-162
> 1) Interpreter settings are not stored in HDFS.
> '/user/zeppelin/conf/interpreter.json' doesnt exist in hdfs.
> 2) Notebook authorisations are not stored in HDFS
> '/user/zeppelin/conf/notebook-authorization.json' doesnt exist in hdfs.
> 3) Look at the interpreter page on Zeppelin and see that there are duplicate
> interpreters
> 4) Previously created notebooks are not copied into hdfs.
> found root cause, there is no property"zeppelin.config.fs.dir" = "conf" in
> zeppelin-config. After i've added it, "conf" directory was created in HDFS
> and interpreter.json was there. Also tested zeppelin, it really using this
> interpreter.json from HDFS. Looks like it works fine. For fresh install it
> will work fine because "zeppelin.config.fs.dir" by default is added to
> zeppelin 0.7.0 (zeppelin-config) but for upgrade we also should add this
> property.
