Suresh Srinivas commented on HDFS-5191:
---------------------------------------
[~cmccabe], given that this is an enabler for HDFS-4949, but an independent
change, can this be committed to trunk and 2.3 release? This helps in this
functionality getting more testing, especially from Hive/ORC side. I or
[~cnauroth] can do the merges.
