Steven Willis commented on HIVE-5112:
-------------------------------------
The hive downloads page says that hive-0.12.0 is compatible with hadoop-2.x.y .
However, I have hive-0.12.0 installed with hadoop-2.2.0 and I get the same
error that [~ashahab] has. I noticed that if I moved all the
{{protobuf-java-2.5.0.jar}} files under hadoop's lib dirs to
{{protobuf-java-2.5.0.jar.bak}}, then I didn't get the error.
It looks like protobuf 2.5.0 is not compatible with generated code from 2.4.1,
and if I move all of the newer jars out of the way, then the
{{protobuf-java-2.4.1.jar}} file is found under hive's lib dir.
I think there needs to be a new release (0.12.1 or 0.13.0) and/or the
compatibility note on the downloads page needs to be adjusted.
> Upgrade protobuf to 2.5 from 2.4
