             Summary: Fix deprecated FileSystem inefficient calls in unit test
                 Key: HADOOP-14106
                 URL: https://issues.apache.org/jira/browse/HADOOP-14106
             Project: Hadoop Common
          Issue Type: Improvement
            Reporter: Mingliang Liu


[HADOOP-13321] deprecates FileSystem APIs that promote inefficient call 
patterns. There are existing code patterns in tests and this JIRA is to address 
them.
