Aman Raj commented on HIVE-26748:
---------------------------------

Hi [~meripones] Thanks for your suggestion. We had proposed in this release 
that we are going with Hive (3.2.0) with Hadoop(3.3.4) and Tez(0.10.2). I think 
that if we try to change Hive to 3.x protobuf, we need to make a release as 
well in Tez consuming this new 3.x protobuf since Tez 0.10.2 is also using 
2.5.0 to build. My hunch is that even if we upgrade Hive, things will fail 
while integrating with Tez and Hadoop. Hadoop has migrated to 3.7.1 protobuf 
which is good. But Tez 0.10.2 still uses 2.5.0 to build. Since Tez builds on 
2.5.0 don't you think it will cause issues when we upgrade Hive to 3.x version 
protobuf? Welcome any suggestions on this.
