----------------------------------------
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}",
