Eli Collins commented on HADOOP-6585:
-------------------------------------
The 6 new warnings are all calls to the now deprecated FileStatus#isDir that I
added to FileContextSymlinkBaseTest.java. Confirmed this by diffing the output
of {{ant -Djavac.args="-Xlint -Xmaxwarns 1000" clear test-core}} run with and
w/o the patch.
> Add FileStatus#isDirectory and isFile

> Per Sanjay's suggestion in HADOOP-6421 let's deprecate FileStatus#isDir() and
> add isDirectory() and isFile() to compliment isSymlink. Currently clients
> assume !isDir() implies a file, which is no longer true with symlinks. I'll
> file a separate jira to change the various uses of !isDir() to be isFile() or
> isFile() or isSymlink() as appropriate.
