James Thomas created HDFS-6853: ---------------------------------- Summary: MiniDFSCluster.isClusterUp() should not check if null NameNodes are up Key: HDFS-6853 URL: https://issues.apache.org/jira/browse/HDFS-6853 Project: Hadoop HDFS Issue Type: Bug Reporter: James Thomas
Suppose we have a two-NN cluster and then shut down one of the NN's (NN0). When we try to restart the other NN (NN1), we wait for isClusterUp() to return true, but this will never happen because NN0 is null and isNameNodeUp returns false for a null NN. -- This message was sent by Atlassian JIRA (v6.2#6252)
