nkeywal commented on HBASE-8105:
--------------------------------
I suppose you have a YouAreDeadException in the logs?
This would be expected. The logic is that the region server cannot be trusted
anymore as it was ejected from the cluster. Then yes, it could abort. On the
other hand you may want to look at it in details. Personally I would prefer to
abort to be sure I don't have clients trying to use this dead server.
Note that for questions or discussions, it's better to use the user mailing
list.
> RegionServer Doesn't Rejoin Cluster after Netsplit
> --------------------------------------------------
>
> Key: HBASE-8105
> URL: https://issues.apache.org/jira/browse/HBASE-8105
> Project: HBase
> Issue Type: Bug
> Components: regionserver
> Affects Versions: 0.92.1
> Environment: Linux Ubuntu 10.04 LTS
> Reporter: philo vivero
>
> Running a 15-node HBase cluster. Testing various failure scenarios. Segregate
> one RegionServer from the cluster by firewalling off every port except SSH
> (because we need to be able to re-enable the node later).
> After the RS is automatically removed from the cluster, we re-enable all
> ports again, but RS never rejoins the cluster.
> I suspect the possibility this is desired behaviour, but haven't found proof
> so far. The code doesn't have any comment indicating this is the behaviour
> desired:
> http://grepcode.com/file/repo1.maven.org/maven2/org.apache.hbase/hbase/0.92.2/org/apache/hadoop/hbase/regionserver/HRegionServer.java/
> See lines starting at 624, public void run(). It makes it through the first
> try/catch block, but then loops inside the second try/catch block. Our
> hypothesis is that it never gets out naturally.
> If we bounce the RegionServer process, then it rejoins the cluster.
