Subject [jira] [Commented] (HDFS-6572) Add an option to the NameNode that prints the software and on-disk image versions
Date Thu, 26 Jun 2014 18:19:25 GMT

    [ https://issues.apache.org/jira/browse/HDFS-6572?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14044974#comment-14044974

Charles Lamb commented on HDFS-6572:
------------------------------------

Thanks for the review [~cnauroth].

The intent was to put this in fs-encryption and then let it percolate to the trunk, but if
you would like it in the trunk sooner, feel free to commit it at your leisure.

> The HDFS namenode should have a startup option that prints the metadata versions of both
the software and the on-disk version. This will be useful for debugging certain situations.
