> 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.
