Description: 
This jira is to address the findbug issues reported in erasure coding feature.

Attached sheet which contains the details of the findbug issues reported in the 
erasure coding feature. I've taken this report from the jenkins build : 
https://builds.apache.org/job/PreCommit-HDFS-Build/10848/artifact/patchprocess/newPatchFindbugsWarningshadoop-hdfs.html.
