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. -- This message is automatically generated by JIRA.
