Description
There is a findbugs warning generated in trunk recently.
https://builds.apache.org/job/PreCommit-HDFS-Build/25298/artifact/out/branch-findbugs-hadoop-hdfs-project_hadoop-hdfs-warnings.html
Looks like this is generated after this commit:https://github.com/apache/hadoop/commit/b60ca37914b22550e3630fa02742d40697decb31#diff-116c9c55048a5e9df753f219c4b3f233
We can make a clean for this.
