URL: https://github.com/apache/hadoop/pull/3876


   ABFS driver test `testAbfsRestOperationExceptionFormat` in 
`ITestAbfsRestOperationException` fails due to the wrong exception format of 
the FileNotFound exception. The test invokes the Filesystem method listFiles(), 
and the exception thrown is found to be of the GetPathStatus format instead of 
ListStatus (difference in number of error fields in response).
   
   The Filesystem implementation of listFiles() calls listLocatedStatus(), 
which then makes a listStatus call. A recent check-in that added implementation 
for listLocatedStatus() in ABFS driver led to a GetFileStatus request before 
ListStatus api are invoked, leading to the aberrant FNF exception format. The 
fix eliminates the GetPathStatus request before ListStatus is called.
