----------------------------------------

bq. That's why I considered to remove the timeout thing in the log split 
manager.
I would +1 this :-)

> 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.
