Change HDP service users passwords (hdfs,yarn,mapred,hive,etc.)

Do I need to set the password on some configuration files when I change the service user account passwords (hdfs,yarn,mapred,hbase,oozie,hive etc.)?

Hi @John Ross Tasipit

Services are started by ambari-sudo.sh, and if you see /etc/shadow these users don't have any password.

So you shouldn't have to set the password anywhere.

But if you enable security in the cluster and you want to have these passwords for kinit, you will have to manually create all services keytabs instead of the keytab generated by ambari which have random keys.
