The issue here is about httpfs liststatus on path to a file.
> HTTPFS liststatus returns incorrect pathSuffix for path of file

> Per the following logs, we can see that liststatus returns the same
> pathSuffix "test.txt" for /tmp/yj/yj1 and /tmp/yj/yj1/test.txt, which is
> wrong. The pathSuffix for the latter should be empty.

> [thost ~]$ hadoop fs -copyFromLocal test.txt /tmp/yj/yj1
> [thost ~]$ curl
> "http://thost.x.y:14000/webhdfs/v1/tmp/yj/yj1?op=LISTSTATUS&user.name=tuser";
> {"FileStatuses":{"FileStatus":[{"pathSuffix":"test.txt","type":"FILE","length":16,"owner":"tuser","group":"supergroup","permission":"644","accessTime":1500007684989,"modificationTime":1500007685286,"blockSize":134217728,"replication":3}]}}
