Chris Nauroth created HDFS-6678: ----------------------------------- Summary: MiniDFSCluster may still be partially running after initialization fails. Key: HDFS-6678 URL: https://issues.apache.org/jira/browse/HDFS-6678 Project: Hadoop HDFS Issue Type: Bug Components: test Affects Versions: 3.0.0, 2.5.0 Reporter: Chris Nauroth Assignee: Chris Nauroth Priority: Minor
{{MiniDFSCluster}} initializes the daemons (NameNodes, DataNodes) as part of object construction. If initialization fails, then the constructor throws an exception. When this happens, it's possible that daemons are left running in the background. There is effectively no way to clean up after this state, because the constructor failed, and therefore the caller has no way to trigger a shutdown. -- This message was sent by Atlassian JIRA (v6.2#6252)
