[jira] [Created] (HDFS-10172) hdfs erasurecode command should
remove the redundant -usage option
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.
