Jun Rao commented on KAFKA-858: ------------------------------- Thanks for patch v2. +1. > High watermark values can be overwritten during controlled shutdown > ------------------------------------------------------------------- > > Key: KAFKA-858 > URL: https://issues.apache.org/jira/browse/KAFKA-858 > Project: Kafka > Issue Type: Bug > Components: replication > Affects Versions: 0.8 > Reporter: Neha Narkhede > Assignee: Neha Narkhede > Priority: Blocker > Labels: kafka-0.8, p1 > Attachments: kafka-858.patch, kafka-858-v2.patch > > > 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. -- This message is automatically generated by JIRA.
