      Description

      When I type

      hdfs dfs -setfacl -m default:user::rwx

      It prints error message:

      -setfacl: <acl_spec> is missing
      Usage: hadoop fs [generic options] -setfacl [-R] [{-b|-k} {-m|-x <acl_spec>} <path>]|[--set <acl_spec> <path>]
      

      But actually, it's the path that I missed. A correct command should be

      hdfs dfs -setfacl -m default:user::rwx /data
      

      In fact,

      -setfacl -x | -m | --set

      expects two parameters.
      We should print error message like this if it misses one:

      -setfacl: Missing either <acl_spec> or <path>
      

      and print the following if it misses two:

      -setfacl: Missing arguments: <acl_spec> <path>
