> Ambari omits the line to enable kerberos on the Spark History Service
> When Ambari sets up a secure spark cluster, it doesn't set
> This will still fail tests unless the line
> spark.history.kerberos.enabled true
> is added to spark-defaults.conf
> without this the Spark History Service will not log in with the keytab, and so not set
up a long-lived secure connection to a Yarn History Server with encryption on.
> This isn't immediately visible (and hard to sport in the tests), because if the user
spark has logged in with kinit, the TGT is picked up and used —which works until the ticket
expires.
