Thejas M Nair commented on HIVE-5112:
-------------------------------------
There are discussions in the hadoop mailing lists about having the hadoop 2 GA
in few weeks. So I think it is worthwhile that we aim to have 0.12 to be
compatible with the hadoop 2 line as well.
[~appodictic] I don't think your -1 is reasonable for the following reasons-
- I don't consider it feasible to stop upgrading jars in hive because the old
version of jar was used by some udf/serde/inputformat. (But I do think that in
long term we need to explore ways of isolating the hive jars/classes vs user
jars/classes)
- In the example you cited, as Sushanth mentioned, you don't need to make any
code changes to use protobuf 2.5. I suspect most users who are using protobuf
with dynamic schema would not choose to work with generated code. So the number
of users this is likely to affect is small.
- The upgrade is inevitable. With it being in trunk, it is in its way into the
0.13 release.
I request you to please reconsider your -1.
