Description
Scenario:
- Install spark1 historyserver on host1. Spark1 uses "/XXX/spark.headless.keytab" as spark.history.kerberos.keytab and "YYY" as spark.history.kerberos.principal.
Install Spark2 historyserver on host1. Spark2 also uses "/XXX/spark.headless.keytab" as spark.history.kerberos.keytab and "ZZZ" as spark.history.kerberos.principal
Since, spark1 and spark2 are using same keytab location but different principals. /XXX/spark.headless.keytab gets override and its principal is changed on install of spark2. Thus, spark1 history server can not be restarted. The restart operation fails to kinit with spark1 principal.
Thus, ambari should use two different location for spark.history.kerberos.keytab
