Steven Rand commented on YARN-5753:
-----------------------------------
I'm seeing the same error in a spark-shell with Spark built against branch-2.
What are people's thoughts on backporting this patch to branch-2? If this makes
sense, should I create a separate JIRA, or can it be done as part of this one?
