> Secondary Namenode is not exiting when there is RuntimeException occurred
> during startup.
> Say I configured wrong configuration, due to that validation failed and
> thrown RuntimeException as shown below. But when I check the environment
> SecondaryNamenode process is alive. When analysed, RMI Thread is still alive,
> since it is not a daemon thread JVM is nit exiting.
> I'm attaching threaddump to this JIRA for more details about the thread.
