Jerry He commented on HBASE-13706:
----------------------------------
I tested both the branch-1 version of the patch and the master version of the
patches with Phoenix. Note these two versions are different changes, with the
master version more dramatic.

> Affects Versions: 2.0.0, 1.0.1, 1.1.0, 0.98.12
> Reporter: Jerry He
> Assignee: Jerry He
> Priority: Minor
> Fix For: 2.0.0, 1.2.0, 1.3.0

> Attachments: HBASE-13706-branch-1.patch, HBASE-13706-master-v2.patch,

>
> CoprocessorClassLoader is used to load classes from the coprocessor jar.
> Certain classes are exempt from being loaded by this ClassLoader, which means
> they will be ignored in the coprocessor jar, but loaded from parent classpath
> instead.
> One problem is that we categorically exempt "org.apache.hadoop".
> But it happens that Hive packages start with "org.apache.hadoop".
> There is no reason to exclude hive classes from theCoprocessorClassLoader.
> HBase does not even include Hive jars.
