Appy commented on HBASE-19290:
------------------------------
- Please add a short commit message explaining 'idea' of the change (makes
reviewing easy then having to reverse engineer the 'idea')
- grabTask only returns 0 or 1. Use boolean please.
- Add @return comment to grabTask.
- We probably don't need {{if (taskGrabed == 0 && !shouldStop) }},
taskReadySeq.wait is indefinite wait on availability of next task.
- Can we pull the while loop one level outside and share the
{{if(calculateAvailableSplitters(..))}} condition.
> Reduce zk request when doing split log

> We observe once the cluster has 1000+ nodes and when hundreds of nodes abort
> and doing split log, the split is very very slow, and we find the
> regionserver and master wait on the zookeeper response, so we need to reduce
> zookeeper request and pressure for big cluster.
