Attaching HADOOP-14769-001.patch.
This fixes recursive directory delete so that it will return false as expected
if the directory does not exist, but it will return true if the directory is
successfully deleted even if one of the path entries existed initially but did
not exist when an attempt was made to delete it. Two new test cases have been
added. One simulates a file being deleted by an external agent and the other a
child directory. One of the existing test cases was removed, as it verified
that recursive directory delete failed if a child directory was deleted by an
external agent--this test actually had a bug in it and the child directory did
exist.
All tests passing against my tmarql3 account:
Tests run: 775, Failures: 0, Errors: 0, Skipped: 155
> WASB: delete recursive should not fail if a file is deleted

> FileSystem.delete(Path path) and delete(Path path, boolean recursive) return
> false if the path does not exist. The WASB implementation of recursive
> delete currently fails if one of the entries is deleted by an external agent
> while a recursive delete is in progress. For example, if you try to delete
> all of the files in a directory, which can be a very long process, and one of
> the files contained within is deleted by an external agent, the recursive
> directory delete operation will fail if it tries to delete that file and
> discovers that it does not exist. This is not desirable. A recursive
> directory delete operation should succeeed if the directory initially exists
> and when the operation completes, the directory and all of its entries do not
> exist.
