> Now master and regionserver use zk to coordinate log split tasks. The split
> log manager manages all log files which need to be scanned and split. Then
> the split log manager places all the logs into the ZooKeeper splitWAL node
> (/hbase/splitWAL) as tasks and monitors these task nodes and waits for them
> to be processed. Each regionserver watch splitWAL znode and grab task when
> node children changed. And regionserver does the work to split the logs.
> Open this umbrella issue to move this "coordinate" work to use new procedure
> v2 framework and reduce zk depencency. Plan to finish this before 3.0
> release. Any suggestions are welcomed. Thanks.
