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.
