Description

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.
