> 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. 
> {code}
> [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}]}}
> [thost ~]$ curl "http://thost.x.y:14000/webhdfs/v1/tmp/yj/yj1/test.txt?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}]}}
> {code}
> Due to this bug, the symptom of running distcp with httpfs to copy a single file /tmp/test.txt is:
> {quote}
> WARN org.apache.hadoop.security.UserGroupInformation: PriviledgedActionException as:systest (auth:PROXY) via httpfs (auth:SIMPLE) cause:org.apache.hadoop.security.AccessControlException: Permission denied: user=systest, access=EXECUTE, inode="/tmp/test.txt":systest:supergroup:-rw-r--r-- (Ancestor /tmp/test.txt is not a directory).
> {quote}
> because /tmp/test.txt is treated as /tmp/test.txt/test.txt.
