Subject [jira] Commented: (HADOOP-5528) Binary partitioner
Date Fri, 27 Mar 2009 11:06:51 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-5528?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12689875#action_12689875

Klaas Bosteels commented on HADOOP-5528:

Husdon seems to be rather busy, so maybe it's better to just copy my local test-patch output
here (for now):

[exec] -1 overall.  
[exec]     +1 @author.  The patch does not contain any @author tags.
[exec]     +1 tests included.  The patch appears to include 6 new or modified tests.
[exec]     +1 javadoc.  The javadoc tool did not generate any warning messages.
[exec]     +1 javac.  The applied patch does not increase the total number of javac compiler
[exec]     -1 findbugs.  The patch appears to introduce 1 new Findbugs warnings.
[exec]     +1 Eclipse classpath. The patch retains Eclipse classpath integrity.
[exec]     +1 release audit.  The applied patch does not increase the total number of release
audit warnings.

(The findbugs warning is about the fact that the name of the deprecated class in mapred shadows
the simple name of the class it extends.)
