Hudson commented on HDFS-2330:
------------------------------

Integrated in Hadoop-Mapreduce-trunk #1167 (See [https://builds.apache.org/job/Hadoop-Mapreduce-trunk/1167/])
    Move HDFS-2330 and HDFS-3190 to branch-2 section, since they have been backported from
trunk. (Revision 1372605)

> In NNStorage.java:
>   There are many stream closures in finally block. 
>   There is a chance that they can mask the root exceptions.
> So, better to follow the pattern like below:
> {code}
>   try{
>      ............
>      ............
>      stream.close();
>      stream =null;
>    }
>    finally{
>      IOUtils.cleanup(LOG, stream);
>    }
> {code}
