> Currently, hlog splitter could spend quite sometime to split a log in case any HDFS issue and recoverLease/retry opening is needed.  If distributed log split manager times out the log worker, other log worker to take over will run into the same issue.
> Ideally, we should not need a timeout monitor.  Since we have a timeout monitor for DSL now, the worker should heartbeat to avoid wrong/unneeded timeouts.
