Subject [jira] [Updated] (HDFS-2114) re-commission of a decommissioned node does not delete excess replica
Date Wed, 20 Jul 2011 23:37:59 GMT

     [ https://issues.apache.org/jira/browse/HDFS-2114?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Matt Foley updated HDFS-2114:
-----------------------------

       Resolution: Fixed
    Fix Version/s: 0.23.0
           Status: Resolved  (was: Patch Available)

+1. Committed to trunk.  Thanks, John!

Note: There were garbage characters in the JavaDoc comments for method TestDecommission.checkFile().
 (Might be my fault since I emailed the text to you.)  I just removed them before committing.

Note that TestDecommission takes 190 seconds to run on a quad-core Mac.  Should consider ways
to decrease this time.
