Jeff Zhang commented on TEZ-2000:
---------------------------------
Finally, reproduce the issue manually.
This issue is caused by TEZ-1892 which add hashCode to Edge. And we use the
hashCode as the edge id, but the hashCode is not unique. So multiple edges may
have the same edge id which cause the issue in pig e2e test. And it should only
impact on master, 0.6 is not affected.
Attach a patch to address the issue, [~sseth] Please help review.

> Pig e2e tests - Cross_5, Union_4 and Union_9 fail. This is due to some jira
> that went in after TEZ-1931, but from the titles I cannot easily associate
> one that could cause this failure.
