Subject [jira] [Updated] (KAFKA-4214) kafka-reassign-partitions fails all the time when brokers are bounced during reassignment
Date Sat, 24 Sep 2016 01:32:20 GMT

     [ https://issues.apache.org/jira/browse/KAFKA-4214?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Apurva Mehta updated KAFKA-4214:
--------------------------------
    Description: 
Due to KAFKA-4204, we never realized that the existing system test for testing reassignment
would always fail when brokers were bounced in mid process. This happens reliably, even for
topics of varying number of partition and varying replication factors.

In particular, we see errors like this in the logs when the brokers are bounced: 

{noformat}
Status of partition reassignment:
ERROR: Assigned replicas (1,2) don't match the list of replicas for reassignment (1) for partition
[test_topic,2]
Reassignment of partition [test_topic,1] completed successfully
Reassignment of partition [test_topic,2] failed
Reassignment of partition [test_topic,3] completed successfully
Reassignment of partition [test_topic,0] is still in progress
{noformat}

Currently, the tests which bounce brokers during reassignment are disabled until this bug
is fixed.
