Plamen Jeliazkov commented on HDFS-4456:
----------------------------------------
So the content length == 0 is a standard return in webHDFS. If you look at the
PUT operation REST API many of those operations return a 200 with content
length = 0. I think we should keep in line with the existing documentation and
therefore I will leave that bit of documentation in there.
I have added a concat test case to BaseTestHttpFSWith.java and hopefully
addressed your other points.
