Subject [jira] [Commented] (HBASE-9941) The context ClassLoader isn't set while calling into a coprocessor
Date Sat, 04 Jan 2014 02:48:51 GMT

Andrew Purtell commented on HBASE-9941:
---------------------------------------

Actually, I agree caliper shouldn't come in except when running tests. Let me figure out some
Maven way to do what I want while having caliper at test scope.

> Whenever one of the methods of a coprocessor is invoked, the context {{ClassLoader}}
isn't set to be the {{CoprocessorClassLoader}}.  It's only set properly when calling the coprocessor's
{{start}} method.  This means that if the coprocessor code attempts to load classes using
the context {{ClassLoader}}, it will fail to find the classes it's looking for.
