Daryn Sharp created HDFS-7046: --------------------------------- Summary: HA NN can NPE upon transition to active Key: HDFS-7046 URL: https://issues.apache.org/jira/browse/HDFS-7046 Project: Hadoop HDFS Issue Type: Bug Components: namenode Affects Versions: 2.5.0, 3.0.0 Reporter: Daryn Sharp Priority: Critical
While processing edits, the NN may decide after adjusting block totals to leave safe mode - in the middle of the edit. Going active starts the secret manager which generates a new secret key, which in turn generates an edit, which NPEs because the edit log is not open. # Transitions should _not_ occur in the middle of an edit. # The edit log appears to claim it's open for write when the stream isn't even open -- This message was sent by Atlassian JIRA (v6.3.4#6332)
