Chetan Nadgire commented on PIG-3114:
-------------------------------------
Taking a look. PigTest checks for existing instance of PigServer and reuses it
instead of creating new instance, will debug more.
Also did not see any unit test failures after applying this patch.
Right now pigunit build is failing on branch 0.11, opened
https://issues.apache.org/jira/browse/PIG-3201 to track this issue.

> I'm using PigUnit to test a pig script within which a macro is defined.
