-------------------------------------
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}
