> 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}",
>
