[jira] [Updated] (KAFKA-858) High watermark values can be overwritten during controlled shutdown

["Neha Narkhede (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/KAFKA-858?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Neha Narkhede updated KAFKA-858:
--------------------------------

               Labels: kafka-0.8 p1  (was: )
          Description: Race condition between controlled shutdown, actual process shutdown and high watermark checkpoint thread frequency can cause high watermark values for a subset of partitions to be overwritten. So even if the controller sends a complete list of partitions to the broker, the highwatermark for some partitions is still 0. This causes the follower to fetch from the leader's start offset.
    Affects Version/s: 0.8
