[jira] [Updated] (KAFKA-580) system test testcase_0122 under replication fails due to large # of data loss

     [ https://issues.apache.org/jira/browse/KAFKA-580?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

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.

> testcase_0122 fails sometimes because a large # of messages is lost with ack = 1. In this case, we expect only a small number of messages to be lost when there are broker failures.
