    [ https://issues.apache.org/jira/browse/HADOOP-4873?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12671364#action_12671364

Matei Zaharia commented on HADOOP-4873:
---------------------------------------

I ran this through test-patch on my laptop and got the following output:

     [exec] -1 overall.  
     [exec] 
     [exec]     +1 @author.  The patch does not contain any @author tags.
     [exec] 
     [exec]     -1 tests included.  The patch doesn't appear to include any new or modified
tests.
     [exec]                         Please justify why no tests are needed for this patch.
     [exec] 
     [exec]     +1 javadoc.  The javadoc tool did not generate any warning messages.
     [exec] 
     [exec]     +1 javac.  The applied patch does not increase the total number of javac compiler
warnings.
     [exec] 
     [exec]     +1 findbugs.  The patch does not introduce any new Findbugs warnings.
     [exec] 
     [exec]     -1 Eclipse classpath. The patch causes the Eclipse classpath to differ from
the contents of the lib directories.
     [exec] 
     [exec]     +1 release audit.  The applied patch does not increase the total number of
release audit warnings.


The Eclipse classpath warning happens for unmodified trunk too, and this UI change is too
small to need tests, so I will commit the patch.

> the deficit and minMap are the most important variables for purposes of scheduling. showing
the minMaps would help in debugging any scheduling issues
