> In CDH 6.x, on the Hadoop 3 rebase, it is now a failure if items are added
> multiple times to the distributed cache. In CDH5, this was a warning. This is
> not an issue for most uses, as adding multiple times typically is user error,
> but this completely breaks Spark actions with keytabs (--keytab).
> Oozie spark actions add everything in the distributed cache of the launcher
> job to the distributed cache of the spark job, meaning the keytab is already
> there, then the --keytab argument tries to add it again causing the failure
> [0].
> [0]
> Caused by: java.lang.IllegalArgumentException: Attempt to add
> (.../filename.keytab#filename.keytab) multiple times to the distributed cache.
