             Summary: Issue with zeppelin after upgrade
                 Key: AMBARI-23234
             Project: Ambari
          Issue Type: Bug
            Reporter: Dmitry Lysnichenko
            Assignee: Dmitry Lysnichenko

I performed the express upgrade to latest fenton build which has the fix for

Observed below issues after upgrading cluster from ambari- with to ambari-

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.
