Description

There are two warnings generated in TestFileSystemApplicationHistoryStore.

hadoop-yarn-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-applicationhistoryservice/src/test/java/org/apache/hadoop/yarn/server/applicationhistoryservice/TestFileSystemApplicationHistoryStore.java
warning: shadow_local: Local variable 'fs' shadows component of class 'org/apache/hadoop/yarn/server/applicationhistoryservice/TestFileSystemApplicationHistoryStore'.
line: 276

Actually these warnings should have be caught in YARN-6239, but the Jenkins checkstyle was broken during that time. The JIRA will address this and make a quick fix.
