Jeffrey Zhong commented on HBASE-8321:
--------------------------------------
The semantics of the existing heartbeat is progress heart beat, if we got a
slow worker we can re-assigne the work to others. It also guards the scenario
when a splitlogworker dies. After the patch, it seems to me we lose both
functionalities. Even when splitworker dies, do still we get heart beats from
the chore?
Thanks,

> 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.
