Jimmy Xiang commented on HBASE-8321:
------------------------------------
[~jeffreyz], you are right: it is kind of heartbeat, but not exactly. It is not
called during recoverLease/getReader, which could take up to 15/5 minutes.
The issue is that the current status reporting is not time based. Some call can
be quick sometimes, but take quite some time sometimes. But the timeout in log
splitting manager is pure time based.
> Log split worker should heartbeat to avoid timeout

> 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.
