The long version of Ted's answer is that your example brings in protobuf version 3, which is known to be incompatible with some hbase internal optimizations.
The specific error you get is exactly that incompatibility: we extend a protobuf class so that we can avoid an unnecessary byte array copy. Unfortunately the stuff we override is marked final in protobuf v3 which results in the class verification error. -- Sean Busbey On Mar 18, 2016 19:38, "Ted Yu" <yuzhih...@gmail.com> wrote: > HBase is
