>             Project: Hadoop HDFS
>          Issue Type: Bug
>    Affects Versions: 3.0.0
>            Reporter: Wei-Chiu Chuang
>            Assignee: Wei-Chiu Chuang

> When I type
> hdfs dfs -setfacl -m default:user::rwx
> It prints error message:
> {noformat}
> -setfacl: <acl_spec> is missing
> Usage: hadoop fs [generic options] -setfacl [-R] [{-b|-k} {-m|-x <acl_spec>} <path>]|[--set
<acl_spec> <path>]
> {noformat}
> But actually, it's the path that I missed. A correct command should be
> {noformat}
> hdfs dfs -setfacl -m default:user::rwx /data
> {noformat}
> \-setfacl \-m \-x \-\-set expects two parameters.
> We should print error message like this if it misses one:
> {noformat}
> -setfacl: Missing either <acl_spec> or <path>
> {noformat}
> and print the following if it misses two:
> {noformat}
> -setfacl: Missing arguments: <acl_spec> <path>
> {noformat}
