Subject [jira] [Commented] (MAPREDUCE-4264) Got ClassCastException when using mapreduce.history.server.delegationtoken.required=true
Date Wed, 16 May 2012 20:43:07 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-4264?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13277100#comment-13277100

Thomas Graves commented on MAPREDUCE-4264:

jenkins failed because it only applies to branch-0.23.  Here is manual run:

-1 overall.  

    +1 @author.  The patch does not contain any @author tags.

    -1 tests included.  The patch doesn't appear to include any new or modified tests.
                        Please justify why no new tests are needed for this patch.
                        Also please list what manual steps were performed to verify this patch.

    -1 javadoc.  The javadoc tool appears to have generated 18 warning messages.

    +1 javac.  The applied patch does not increase the total number of javac compiler warnings.

    +1 eclipse:eclipse.  The patch built with eclipse:eclipse.

    +1 findbugs.  The patch does not introduce any new Findbugs (version ) warnings.

    +1 release audit.  The applied patch does not increase the total number of release audit

The javadoc warnings were not introduced by this jira - they are all pre-existing and have
been fixed or excluded on trunk.
