> URL: https://issues.apache.org/jira/browse/PHOENIX-981
> Project: Phoenix
> Issue Type: Bug
> Affects Versions: 3.0.0
> Environment: HBase 0.94.16, Linux

> As discussed with [~jamestaylor]. Starting with Phoenix 3.0.0 release,
> Phoenix client will be compatible with Phoenix server side running on higher
> 3.x.x version which means that if server is upgraded first with the new
> phoenix jar, older phoenix client will continue to function. Only major
> version will remain in-compatible.
> Currently any query involving join with client on tag
> v3.0.0-incubating-release and server running on head of 3.0 branch (hash
> 4ce243c1c79fbd4b2f3f1c0cdbedc17c22d9c526) results in the following exception:
