Description
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.
