This sounds to be an interesting feature, and I would love to work on it. > Add a parameter to `hdfs dfsadmin -saveNamespace' to allow an arbitrary storage dir > ----------------------------------------------------------------------------------- > > Key: HDFS-2746 > URL: https://issues.apache.org/jira/browse/HDFS-2746 > Project: Hadoop HDFS > Issue Type: New Feature > Components: namenode > Affects Versions: 2.0.0-alpha > Reporter: Aaron T. Myers > > Presently `hdfs dfsadmin -saveNamespace' will attempt to save a snapshot of the file system metadata state into all configured storage dirs. It would be nice if we could optionally specify an arbitrary local dir on the NN to save the FS state into, instead of the configured storage dirs. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
