Martin Bukatovic commented on AMBARI-8043:
------------------------------------------
This configuration then instructs Hadoop to create kerberos ticket for hdfs
user even though this is pointless for hdfs:
{noformat}
root@node02 # ls -l /tmp/krb*
-rw------- 1 hdfs hadoop 805 Mar 12 15:48 /tmp/krb5cc_20405
{noformat}
> Remove nonrequired attributes for Kerberos when using non-HDFS storage type
