Ramya R commented on HADOOP-5114:
---------------------------------

I ran all the unit tests on Windows a couple of times and observed close to 50 
tests failing each time. Besides the above mentioned tests, there are a variety 
of hdfs, conf, security, cli, tools, fs tests which are failing as well on 
Windows due to similar kind of errors.
Following is the list of failing tests besides the above reported tests. Some 
are sporadically failing and some are consistently failing.

* Exception: java.io.IOException: Could not obtain block: <Blk_id> 
file=/<filename>
** Consistently failing tests:
*** TestDFSUpgradeFromImage - testUpgradeFromImage

* Exception: java.io.IOException: Bad connect ack with firstBadLink 
127.0.0.1:<port number>
