>             Project: Hadoop Common
>          Issue Type: Bug
>    Affects Versions: 2.7.0
>            Reporter: Lei (Eddy) Xu
>            Assignee: Lei (Eddy) Xu
>            Priority: Minor

> When enabled {{hadoop.shell.missing.defaultFs.warning}}, a few tests were failed as following:
> {noformat}
> java.lang.RuntimeException: failed to get .NAME
> 	at java.lang.Class.getDeclaredField(Class.java:1948)
> 	at org.apache.hadoop.fs.shell.Command.getCommandField(Command.java:458)
> 	at org.apache.hadoop.fs.shell.Command.getName(Command.java:401)
> 	at org.apache.hadoop.fs.shell.FsCommand.getCommandName(FsCommand.java:80)
> 	at org.apache.hadoop.fs.shell.FsCommand.processRawArguments(FsCommand.java:111)
> 	at org.apache.hadoop.fs.shell.Command.run(Command.java:154)
> 	at org.apache.hadoop.fs.TestFsShellReturnCode.testChgrpGroupValidity(TestFsShellReturnCode.java:434)
> {noformat}
> The reason is that, in {{FsCommand#processRawArguments}}, it uses {{getCommandName()}},
which uses reflection to find {{static String NAME}} field, to build error message. But in
the tests, the commands are built without {{static String NAME}} field, since it is not inherited.
