Joel Koshy updated KAFKA-497: ----------------------------- Priority: Blocker (was: Major) > recover consumer during unclean leadership change > ------------------------------------------------- > > Key: KAFKA-497 > URL: https://issues.apache.org/jira/browse/KAFKA-497 > Project: Kafka > Issue Type: Bug > Components: core > Reporter: Jun Rao > Priority: Blocker > Labels: bugs > Fix For: 0.8 > > Original Estimate: 168h > Remaining Estimate: 168h > > When we do an unclean leadership change (i.e., no live broker in ISR), > offsets already exposed to consumers may no longer be valid. As a result, a > consumer could either receive an OffsetOutOfRange exception or hit an > InvalidMessageSizeException while iterating a fetched message set. In either > case, we need to be able to recover the consumption (probably from the > current latest offset from the leader). We need to recover both regular and > follower consumers. -- This message is automatically generated by JIRA.
