Description

The Spark principal name is not always lowercase in HDP 2.5.

This is because the principal definition does not specify `toLower` in the HDP
2.5 specific Kerberos descriptor:

*stacks/HDP/2.5/services/SPARK/kerberos.json:12*

"value": "${spark-env/spark_user}-${cluster_name}@${realm}",

Should be:

*stacks/HDP/2.5/services/SPARK/kerberos.json:12*

"value": "${spark-env/spark_user}-${cluster_name|toLower()}@${realm}",
