> 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.
