Add javadoc for availableRSs.

grabTask(ZNodePaths.joinZNode(watcher.znodePaths.splitLogZNode,
paths.get(idx)));

Grabed -> Grabbed

{code}
Consider using shorter sleep time.

> 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.
