> 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.
