[jira] [Created] (AMBARI-18491) Spark user principal name is not always lowercase in HDP 2.5

Andrew Onischuk created AMBARI-18491:
----------------------------------------

             Summary: Spark user principal name is not always lowercase in HDP 2.5
                 Key: AMBARI-18491
                 URL: https://issues.apache.org/jira/browse/AMBARI-18491
             Project: Ambari
          Issue Type: Bug
            Reporter: Andrew Onischuk
            Assignee: Andrew Onischuk
             Fix For: 2.4.2
         Attachments: AMBARI-18491.patch

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}",
