dhruba borthakur commented on HDFS-1509: ---------------------------------------- Absolutely agree that constantly trying to write to a failed directory will slow things down, I am not suggesting we do this. Instead, "bin/hadoop dfsadmin -savenamespace" is a command line utility and is likely to be run manually by an administrator; when this command is run the namenode saves its entire image from memory in fsimage (and truncates fsedits). I would like this operation to try writing the fsimage to all configured directories. > 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 > Components: name-node > 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. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
