> If one region is splitting when regionserver is stoping.
> The following code may executed in SplitTransaction#openDaughters.
> {code}
> // TODO: Is this check needed here?
> if (stopped || stopping) {
> // add 2nd daughter first (see HBASE-4335)
> MetaEditor.addDaughter(server.getCatalogTracker(),
> b.getRegionInfo(), null);
> MetaEditor.addDaughter(server.getCatalogTracker(),
> a.getRegionInfo(), null);
> LOG.info("Not opening daughters " +
> b.getRegionInfo().getRegionNameAsString() +
> " and " +
> a.getRegionInfo().getRegionNameAsString() +
> " because stopping=" + stopping + ", stopped=" + stopped);
> }
> {code}
> So, for the two daughter regions, their location are both null in .META.
> When ServerShutdownHandler process the dead server, it will not assign these
> two daughter regions since their location(info:server) are null in .META. by
> MetaReader.getServerUserRegions().
