Jun Rao updated KAFKA-580:
--------------------------
Attachment: kafka-580.patch
Attach a patch. The problem is that if we remove items from a set while
iterating it, the behavior is not deterministic.Also fixed kafka-578 in the
patch since it's touching the same code.
> system test testcase_0122 under replication fails due to large # of data loss
