Target Version/s:

2.0.0
Release Note:

Hide
Hive-on-MR has been deprecated in Hive 2 releases as the other, more modern and actively developed execution engines have been production-ready for some time. The support may be removed in future 2.X versions. Consider using a different execution engine (i.e. spark, tez) or using Hive 1.X releases if you want to keep using MR.
