>                 Key: HADOOP-14151
>                 URL: https://issues.apache.org/jira/browse/HADOOP-14151
>             Project: Hadoop Common
>          Issue Type: Bug
>          Components: fs/swift
>    Affects Versions: 3.0.0-alpha3

> Unit test {{TestSwiftContractRootDir#testRmNonEmptyRootDirNonRecursive}} fails at {{assertIsFile(file)}}. This leads me to suspect swift treats 0-len file as directory. Confirmed by the following experiment:
> {noformat}
> $ ls -l /tmp/zero /tmp/abc
> -rw-rw-r--  1 jzhuge  wheel  4 Mar  7 13:19 /tmp/abc
> -rw-rw-r--  1 jzhuge  wheel  0 Mar  7 13:19 /tmp/zero
> $ bin/hadoop fs -put /tmp/zero /tmp/abc swift://jzswift.rackspace/
> 2017-03-07 13:24:09,321 INFO snative.SwiftNativeFileSystemStore: mv  jzswift/zero._COPYING_ swift://jzswift.rackspace/zero
> $ bin/hadoop fs -touchz swift://jzswift.rackspace/touchz
> $ bin/hadoop fs -ls swift://jzswift.rackspace/
> Found 3 items
> -rw-rw-rw-   1          4 2017-03-07 13:36 swift://jzswift.rackspace/abc
> drwxrwxrwx   -          0 2017-03-07 13:28 swift://jzswift.rackspace/touchz
> drwxrwxrwx   -          0 2017-03-07 13:32 swift://jzswift.rackspace/zero
