> A possible exception: If the related regionserver was just killed(But HMaster
> has not perceived that), then we will get a local exception "Connection reset
> by peer". If this region belongs to a disabling table. what will happen?
> ServerShutdownHandler will remove this region from AM#regions. So this region
> is still existing in RIT. TimeoutMonitor will take care of it after it got
> timeout. Then invoke unassign again. Since this region has been removed from
> AM#regions, it will return directly due to the below code:
> {code}
> synchronized (this.regions) {
> // Check if this region is currently assigned
> if (!regions.containsKey(region)) {
> LOG.debug("Attempted to unassign region " +
> region.getRegionNameAsString() + " but it is not " +
> "currently assigned anywhere");
> return;
> }
> }
> {code}
> Then it leads to an end-less loop.
