Oops! Thanks for the shaded-client version correction, Sean!

If upgrading is an option, for HBase 1.1+ applications you can use a
newer Protocol Buffers by relying on hbase-shaded-client as a

With Apache HBase 1.0-based applications, you must use Protocol Buffers 2.5
in its standard package (e.g. com.google.protobuf). If you want to use
another version of protobuf, you would have to shade and relocate that
dependency.
In newer versions of HBase (2.0 I believe it will land), does the above
recommendation (shade+relocate) internally. This would let you use whatever
version of Protobuf you'd like, regardless of what HBase is using.

Hi group,
I have a problem using ProtocolBuffers 3 in my application with CDH5.6
HBase 1.0.
When creating BufferedMutator and flush data into HBase, it shows an
error
as below:

It looks like HBase is using ProtocolBuffers2.5, which cause the bytecode
incompatible.
Does anyone has experience of resolving this problem? Or I have to switch
back to protocol 2.5.
