HA: NN throws NPE during shutdown if it fails to startup --------------------------------------------------------
Key: HDFS-2948 URL: https://issues.apache.org/jira/browse/HDFS-2948 Project: Hadoop HDFS Issue Type: Sub-task Components: ha, name-node Affects Versions: HA branch (HDFS-1623) Reporter: Todd Lipcon Priority: Minor Last night's nightly build had a bunch of NPEs thrown in NameNode.stop. Not sure which patch introduced the issue, but the problem is that NameNode.stop() is called if an exception is thrown during startup. If the exception is thrown before the namesystem is created, then NameNode.namesystem is null, and {{namesystem.stop}} throws NPE. -- This message is automatically generated by JIRA.
