> Key: HDFS-9852
> URL: https://issues.apache.org/jira/browse/HDFS-9852
> Project: Hadoop HDFS
> Issue Type: Bug
> Affects Versions: 3.0.0-alpha1
> Reporter: Wei-Chiu Chuang
> Assignee: Wei-Chiu Chuang
> Priority: Minor
> Labels: supportability
> Fix For: 3.0.0-alpha1
>
> Attachments: HDFS-9852.001.patch, HDFS-9852.002.patch

> When I type
> {noformat}hdfs dfs -setfacl -m default:user::rwx{noformat}
> 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}
> In fact,
> {noformat}-setfacl -x | -m | --set{noformat} 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}
