Jerry He commented on HBASE-13706:
----------------------------------
Hi, [~apurtell]
bq. We shouldn't be exempting foreign classes in our classloader. HBase
doesn't know anything about Hive, nor should it.
Exactly. Here is an example. In my coprocessor implementation jar, I have
org.apache.hadoop.hive classes embedded. But the CoprocessorClassLoader will
exempt/skip these classes when loading the coprocessor implementation jar,
which is not right.
I will get a patch ... simple patch.

> Key: HBASE-13706
> URL: https://issues.apache.org/jira/browse/HBASE-13706
> Project: HBase
> Issue Type: Bug
> Components: Coprocessors
> Affects Versions: 2.0.0, 1.0.1, 1.1.0, 0.98.12
> Reporter: Jerry He
> Priority: Minor
>
> 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.
