> Ignore zk assign event if region is not known in transition
> -----------------------------------------------------------
>
> Key: HBASE-9184
> URL: https://issues.apache.org/jira/browse/HBASE-9184
> Project: HBase
> Issue Type: Bug
> Components: Region Assignment
> Reporter: Jimmy Xiang
> Assignee: Jimmy Xiang
> Fix For: 0.98.0, 0.95.2
>
> Attachments: trunk-9184.patch
>
>
> This is a follow up of HBASE-9161. Currently, if a region is in transition,
> we ignore any unexpected zk assign event and log a warning. For example, a zk
> closing event will be ignored if the region is pending open actually.
> However, if the region is not in transition, we will accept such events. For
> events not related to split/merge, we should ignore them and log a warning
> too, to tighten up the region state transition. During normal operation,
> this (ensuring region is in transition before accepting transition related
> events) is fine. During master failover, this is fine as long as we don't do
> region transition bypass ZK. We should also make sure to watch assignment
> znodes after user region states are recovered, so that we don't log many such
> warnings.
