--------------------------------------------------------------
Key: PIG-2402
URL: https://issues.apache.org/jira/browse/PIG-2402
Project: Pig
Issue Type: Bug
Components: impl
Affects Versions: 0.10, 0.9.2, 0.11
Reporter: Daniel Dai
Assignee: Daniel Dai
Fix For: 0.10, 0.9.2, 0.11
Current logic is:
context instanceof WrappedMapper.Context
It is no longer working in current 0.23 branch. I see test failure in some
tests, such as SkewedJoin_6.
Here is the stack:
