Steven Willis commented on HIVE-6219: ------------------------------------- I just added the following to HIVE-5112, but it seems like this issue is a better place to track the incompatibility between hadoop and hive with respect to protocol buffers: 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 Abin Shahab 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) with the upgrade to protobuf-2.5.0 and/or the compatibility note on the downloads page needs to be adjusted. > TestProtocolBuffersObjectInspectors fails when upgrading protobuf to 2.5.0 > -------------------------------------------------------------------------- > > Key: HIVE-6219 > URL: https://issues.apache.org/jira/browse/HIVE-6219 > Project: Hive > Issue Type: Bug > Components: Serializers/Deserializers > Affects Versions: 0.13.0 > Reporter: Gordon Wang > > As Hadoop 2.2.0 is GA, the protobuf version in Hadoop 2.2.0 is protobuf 2.5.0. > I notice that there is already a jira HIVE-5112 about protobuf upgrading.
