Description

Counterpart JIRA to HDFS-11096. We need to:

• examine YARN and MR's JACC report for binary and source incompatibilities
• run the PB differ that Sean wrote for HDFS-11096 for the YARN PBs.
• sanity test some rolling upgrades between 2.x and 3.x. Ideally these are automated and something we can run upstream.
