Konstantin Boudnik commented on MAPREDUCE-2223:
-----------------------------------------------

I have also ran test-patch locally:
{noformat}
-1 overall.  

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

    +1 tests included.  The patch appears to include 3 new or modified tests.

    +1 javadoc.  The javadoc tool did not generate any warning messages.

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

    -1 findbugs.  The patch appears to introduce 13 new Findbugs warnings.

    -1 release audit.  The applied patch generated 2 release audit warnings 
(more than the trunk's current 1 warnings).

    +1 system test framework.  The patch passed system test framework compile.
{noformat}

2 release audit warnings are because of missed licenses smoke-tests and 
robots.txt files (see HDFS-1511 for correct fix of the problem). FindBugs are 
legit but unrelated to the patch. Mapreduce trunk needs to be fixed wrt static 
analysis warnings.

> Depending on the order of entries in /etc/hosts, TestCLI can fail. This is 
> because it sets fs.default.name to "localhost", and then the bound IPC socket 
> on the NN side reports its hostname as "foobar-host" if the entry for 
> 127.0.0.1 lists "foobar-host" before "localhost". This seems to be the 
> default in some versions of Ubuntu.
