setfacl: option 'x"' is not available for this command

Hi, trying to setfacl in hdfs shell with following command:

`hdfs-shell /the/path > setfacl -m user:usrName:--x dir`

and it fails with:

> Option 'x' is not available for this command. Use tab assist or the "help" command to see the legal options

Using hdfs dfs with same stuff is successful:

`$ hdfs dfs -setfacl -m user:usrName:--x /the/path/dir`

Unfortunately the version command is not helpful in my case:

```
hdfs-shell /the/path >version
unspecified
```

Can you confirm, please?

Start by reproducing the hdfs-shell setfacl command shown in the issue and compare its option handling with the successful hdfs dfs invocation. Trace how setfacl arguments are parsed, then verify that `-m user:usrName:--x` is accepted and produces the expected ACL change.
