Chris Nauroth commented on HIVE-26748:
--------------------------------------
If we're going with Hadoop 3.3.4, then that's going to switch to a custom
shaded dependency for protobuf, so I don't expect problems there.
https://github.com/apache/hadoop/blob/rel/release-3.3.4/hadoop-project/pom.xml#L264-L268
However, note that it would be leapfrogging the master branch, which is
currently on Hadoop 3.3.1. (That version still has the shaded dependency.)
Regarding Tez, I suppose the upgrade ends up working fine on master because the
Tez protobuf messages get serialized/deserialized end-to-end in the context of
a single Hive/Tez session, so the encoding is consistent even if Hive declares
a different version dependency than Tez. There is never a case of passing one
of these messages externally where another client might expect the earlier
protobuf version.
To build confidence, it would be great to hear from anyone who has tested a
full distro with the new Hive 4 alphas, which I haven't tried yet. If so, were
there any surprises on protobuf compatibility?
