Subject [jira] [Updated] (AMBARI-15871) App Timeline Server start fails on a kerberized cluster due to absence of hdfs keytab
Date Thu, 14 Apr 2016 17:56:25 GMT

     [ https://issues.apache.org/jira/browse/AMBARI-15871?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Goutam Tadi updated AMBARI-15871:
---------------------------------
    Description: 
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.
