We installed zeppelin as an ambari service as per the link below . It was working fine and we were able to run spark and hive jobs. Recently we upgraded to HDP 2.3.4 and the zeppelin service is not working. Is there any manual steps required to get zeppelin working with new HDP and spark version as zeppelin was not upgraded as part of the automatic HDP upgrade process. https://github.com/hortonworks-gallery/ambari-zeppelin-service . This is the error we are getting. 16/01/28 14:41:44 INFO YarnExtensionServices: Service org.apache.spark.deploy.yarn.history.YarnHistoryService started 16/01/28 14:41:45 INFO Client: Application report for application_1453980715711_0009 (state: ACCEPTED) 16/01/28 14:41:45 INFO Client: client token: N/A diagnostics: N/A ApplicationMaster host: N/A ApplicationMaster RPC port: -1 queue: default start time: 1453992104608 final status: UNDEFINED tracking URL: http://dshost1:8088/proxy/application_1453980715711_0009/ user: zeppelin 16/01/28 14:41:46 INFO Client: Application report for application_1453980715711_0009 (state: ACCEPTED) 16/01/28 14:41:47 INFO Client: Application report for application_1453980715711_0009 (state: FAILED) 16/01/28 14:41:47 INFO Client: client token: N/A diagnostics: Application application_1453980715711_0009 failed 2 times due to AM Container for appattempt_1453980715711_0009_000002 exited with exitCode: 1 For more detailed output, check application tracking page:http://dshost1:8088/cluster/app/application_1453980715711_0009Then, click on links to logs of each attempt.
