Andrew Wang commented on HDFS-6678: ----------------------------------- +1 LGTM > 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 > Attachments: HDFS-6678.1.patch > > > {{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)
