Subject [jira] [Commented] (HDFS-9715) Check storage ID uniqueness on datanode startup
Date Tue, 02 Feb 2016 00:05:39 GMT

    [ https://issues.apache.org/jira/browse/HDFS-9715?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15127293#comment-15127293

Andrew Wang commented on HDFS-9715:

Smallest nit ever, the javadoc for the activateVolume method still says "Active" rather than
"Activate". Otherwise I'm +1 too, thanks Eddy.

> We should fix this to check storage ID uniqueness on datanode startup. If someone has
manually edited the storage ID files, or if they have duplicated a directory (or re-added
an old disk) they could end up with a duplicate storage ID and not realize it. 
> The HDFS-7575 fix does generate storage UUID for each storage, but not checks the uniqueness
of these UUIDs.
