Ability to do savenamespace without being in safemode -----------------------------------------------------
Key: HDFS-1508 URL: https://issues.apache.org/jira/browse/HDFS-1508 Project: Hadoop HDFS Issue Type: Improvement Reporter: dhruba borthakur Assignee: dhruba borthakur In the current code, the administrator can run savenamespace only after putting the namenode in safemode. This means that applications that are writing to HDFS encounters errors because the NN is in safemode. We would like to allow saveNamespace even when the namenode is not in safemode. The savenamespace command already acquires the FSNamesystem writelock. There is no need to require that the namenode is in safemode too. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
