HA NN should be able to handle some cases of storage dir recovery on start --------------------------------------------------------------------------
Key: HDFS-3103 URL: https://issues.apache.org/jira/browse/HDFS-3103 Project: Hadoop HDFS Issue Type: Improvement Components: ha, name-node Affects Versions: 0.24.0, 0.23.3 Reporter: Todd Lipcon As a shortcut in developing HA, we elected not to deal with the case of storage directory recovery while HA is enabled. But there are many cases where we can and should handle it. For example, if the user configures two local dirs and one shared dir, but one of the local dirs is empty at startup, we should be able to re-format the empty dir from the other local dir. -- This message is automatically generated by JIRA.
