Subject [jira] [Created] (HBASE-13706) CoprocessorClassLoader should not exempt Hive classes
Date Mon, 18 May 2015 17:22:00 GMT
Jerry He created HBASE-13706:

             Summary: CoprocessorClassLoader should not exempt Hive classes
                 Key: HBASE-13706
                 URL: https://issues.apache.org/jira/browse/HBASE-13706
             Project: HBase
          Issue Type: Bug
          Components: Coprocessors
    Affects Versions: 0.98.12, 1.0.1, 2.0.0, 1.1.0
            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.
