> As HBASE-27223 said, if {{WAL.sync}} get a timeout exception, we should
> abort the region server, as the design of WAL sync, is to succeed or die,
> there is no 'failure'. It is usually not a big deal is because we set a very
> large default value(5 minutes) for {{AbstractFSWAL.WAL_SYNC_TIMEOUT_MS}},
> usually the WAL system will abort the region server if it can not finish the
> sync within 5 minutes.
> In the PR, only the {{WAL.sync}} timeout in {{HRegion#doWALAppend}}
> ,regionServer is always aborted. For {{WALUtil.writeMarker}}, it is just
> record the internal state and seems it is no need to always abort the
> regionServer when {{WAL.sync}} timeout，it is the internal state transition
> that determines whether regionServer is aborted.
