> Scheduled tasks in distributed log splitting not in sync with ZK
> ----------------------------------------------------------------
>
> Key: HBASE-3890
> URL: https://issues.apache.org/jira/browse/HBASE-3890
> Project: HBase
> Issue Type: Bug
> Components: regionserver
> Affects Versions: 0.92.0
> Reporter: Lars George
> Assignee: Jeffrey Zhong
> Priority: Critical
> Fix For: 0.96.0
>
> Attachments: hbase-3890_1.patch, hbase-3890.patch
>
>
> This is in continuation to HBASE-3889:
> Note that there must be more slightly off here. Although the splitlogs znode
> is now empty the master is still stuck here:
> {noformat}
> Doing distributed log split in
> hdfs://localhost:8020/hbase/.logs/10.0.0.65,60020,1305406356765
> - Waiting for distributed tasks to finish. scheduled=2 done=1 error=0 4380s
> Master startup
> - Splitting logs after master startup 4388s
> {noformat}
> There seems to be an issue with what is in ZK and what the TaskBatch holds.
> In my case it could be related to the fact that the task was already in ZK
> after many faulty restarts because of the NPE. Maybe it was added once (since
> that is keyed by path, and that is unique on my machine), but the reference
> count upped twice? Now that the real one is done, the done counter has been
> increased, but will never match the scheduled.
> The code could also check if ZK is actually depleted, and therefore treat the
> scheduled task as bogus? This of course only treats the symptom, not the root
> cause of this condition.
