[jira] [Commented] (AMBARI-9079) After moving ATS, ATS web ui is not working

["Srimanth Gunturi (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/AMBARI-9079?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14271866#comment-14271866 ] 

Srimanth Gunturi commented on AMBARI-9079:
------------------------------------------

ATS keeps some data in a LevelDB located in /hadoop/yarn/timeline/leveldb-timeline-store.ldb
When we move ATS it creates a new LevelDB on the new host and application history fails to find the apps.
We need to copy the db from the source host to the target host and give it the right permissions/user.

The solution is to add a manual step to the ATS move wizard with the following steps

1. Copy /hadoop/yarn/timeline/leveldb-timeline-store.ldb from the <source host> to the <target host>
2. On the <target host> extecute:
        chown -R yarn:hadoop /hadoop/yarn/timeline/leveldb-timeline-store.ldb
        chmod -R 700 /hadoop/yarn/timeline/leveldb-timeline-store.ldb

> Installed 2-node cluster with HDP 2.2. ATS on c6402. Moved to c6401 and the "App Timeline Web UI" goes crit, because it looks like ATS is not working.
