Kirankumar Bhusanurmath commented on AMBARI-24893:
--------------------------------------------------
Directory structure and correct permission are necessary for the service to
start, after deploying fresh HDPO cluster service won't start because of
missing file or permission. Manually have to create and assign correct
permissions.
> Add relevant NameNode start logic to OneFS mpack

> Key: AMBARI-24893
> URL: https://issues.apache.org/jira/browse/AMBARI-24893
> Project: Ambari
> Issue Type: Bug
> Affects Versions: 2.7.0
> Environment: HDP 3.0.1 + OneFS 8.1.2
> Reporter: David Tucker
> Priority: Major
>
> Deploying with OneFS using the mpack seems to omit setup steps. I'm not sure
> exactly where the steps are defined in 2.7, but in 2.6 they seem to be here:
> https://github.com/apache/ambari/blob/ac651d9d88d0c65d7ec1141ac5cd2af659781d79/ambari-server/src/main/resources/common-services/HDFS/2.1.0.2.0/package/scripts/hdfs_namenode.py#L102-L238
> It's possible not all the steps are relevant, but at the very least these
> seem to be:
> https://github.com/apache/ambari/blob/ac651d9d88d0c65d7ec1141ac5cd2af659781d79/ambari-server/src/main/resources/common-services/HDFS/2.1.0.2.0/package/scripts/hdfs_namenode.py#L234-L235
> According to
> [Kiran|https://issues.apache.org/jira/secure/ViewProfile.jspa?name=kbhusanurmath],
> "this is causing issue starting some of the services and importantly
> timeline server V2 is unable to create necessary znode and start ats-hbase
> app."
> It also appears to cause the YARN service check to fail with an ACE (since
> {{/user/ambari-qa}} was not set up correctly).
