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 > -------------------------------- > > Key: HIVE-5112 > URL: https://issues.apache.org/jira/browse/HIVE-5112 > Project: Hive > Issue Type: Improvement > Reporter: Brock Noland > Assignee: Owen O'Malley > Fix For: 0.13.0 > > Attachments: HIVE-5112.2.patch, HIVE-5112.D12429.1.patch > > > Hadoop and Hbase have both upgraded protobuf.
