-------------------------------------

             Summary: hdfs dfs -setfacl error message is misleading
                 Key: HDFS-9852
                 URL: https://issues.apache.org/jira/browse/HDFS-9852
             Project: Hadoop HDFS
          Issue Type: Bug
    Affects Versions: 3.0.0
            Reporter: Wei-Chiu Chuang
            Assignee: Wei-Chiu Chuang
            Priority: Trivial


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}
