Kerberos authentication for non-default users

The steps described here are only applicable if you are running one or more CDP services with non-default users.

If you have modified the default value for the System User property for any service in Cloudera Manager, you must only perform the command (as described below) corresponding to that service, in order to successfully run jobs with the non-default user.
HBase Give the hbase user ownership of the HBase root directory:
sudo -u hdfs hadoop fs -chown -R hbase ${hbase.rootdir}
By default, hbase.rootdir is /hbase.
Hive Give the hive user ownership of the /user/hive directory.
sudo -u hdfs hadoop fs -chown hive /user/hive
YARN For every NodeManager host, for each path in yarn.nodemanager.local-dirs, run:
rm -rf ${yarn.nodemanager.local-dirs}/usercache/*
This removes the /usercache directory that contains intermediate data stored for previous jobs.
