Jakob Homan updated HDFS-8435:
------------------------------
Attachment: HDFS-8435.003.patch
New patch that applies to both trunk and branch 2.
The failed tests were because the default of createParent param in WebHDFS was
being set to false, but then not being used by the actual call and overridden
to true in the create call on the dfsclient. I've fixed this to pay attention
to the parameter and updated the spec to be correct.
Good catch on the throw. Removed.
I had played around with that uber test a bit. Using the annotation loses the
explicit method about what went wrong on each test. I put as much into the
helper method as looked reasonable (judgment call here); when I put more of the
per-test logic into the helper (expected exception, subsequent message), it got
really crowded and ugly.

> The WebHdfsFileSystem implementation doesn't support createNonRecursive.
> HBase extensively depends on that for proper functioning. Currently, when the
> region servers are started over web hdfs, they crash due with -
