-------------------------------------
Assignee: Robert Levas
> App Timeline Server start fails on a kerberized cluster due to absence of
> hdfs keytab
> -------------------------------------------------------------------------------------
>
> Key: AMBARI-15871
> URL: https://issues.apache.org/jira/browse/AMBARI-15871
> Project: Ambari
> Issue Type: Bug
> Components: stacks
> Affects Versions: 2.2.2
> Reporter: Goutam Tadi
> Assignee: Robert Levas
> Fix For: 2.2.2
>
>
> Kerberizing a cluster with App timeline server (not collocated with
> HDFS-client) fails to restart service since it fails to obtain hdfs headless
> keytab. This is because the hdfs keytabs are generated on Namenodes and hdfs
> client nodes but not on App Timeline Server nodes. A small fix in Yarn
> kerberos.json can get rid off this.
