Subject [jira] Created: (HDFS-1509) Resync discarded directories in fs.name.dir during saveNamespace command
Date Thu, 18 Nov 2010 23:23:14 GMT
Resync discarded directories in fs.name.dir during saveNamespace command
------------------------------------------------------------------------

                 Key: HDFS-1509
                 URL: https://issues.apache.org/jira/browse/HDFS-1509
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: dhruba borthakur
            Assignee: dhruba borthakur


In the current implementation, if the Namenode encounters an error while writing to a fs.name.dir
directory it stops writing new edits to that directory. My proposal is to make  the namenode
write the fsimage to all configured directories in fs.name.dir, and from then on, continue
writing fsedits to all configured directories.
