Subject [jira] [Created] (HDFS-10172) hdfs erasurecode command should remove the redundant -usage option
Date Wed, 16 Mar 2016 09:20:33 GMT
Wei-Chiu Chuang created HDFS-10172:
--------------------------------------

             Summary: hdfs erasurecode command should remove the redundant -usage option
                 Key: HDFS-10172
                 URL: https://issues.apache.org/jira/browse/HDFS-10172
             Project: Hadoop HDFS
          Issue Type: Improvement
    Affects Versions: 3.0.0
            Reporter: Wei-Chiu Chuang
            Priority: Minor


{{hdfs erasurecode}} has two similar options {{-help}} and {{-usage}}.
{noformat}
hdfs erasurecode -usage getPolicy
Usage: hdfs erasurecode [generic options] -getPolicy <path>

hdfs erasurecode -help getPolicy
-getPolicy <path> :
  Get erasure coding policy information about at specified path
{noformat}
I don't think the -usage option is that useful, because -help option already covers that.
No other HDFS commands has the same -usage command.
