> When a worker RS gets aborted after the SplitWALRemoteProcedure got
> dispatched, RegionServerTracker takes care of it and [aborts the pending
> Operation|https://github.com/apache/hbase/blob/rel/2.5.8/hbase-server/src/main/java/org/apache/hadoop/hbase/master/procedure/RSProcedureDispatcher.java#L160]

> [expireServer|https://github.com/apache/hbase/blob/rel/2.5.8/hbase-server/src/main/java/org/apache/hadoop/hbase/master/RegionServerTracker.java#L172].
>
> It did help the parent procedure, SplitWalProcedure, to choose another worker
> RS but the aborting RS is also splitting the WAL. Now while creating the
> recovered edits both will try to write the same file. One RS that starts late
> for the file deletes the previous file that cause failures.
