[ http://issues.apache.org/jira/browse/HADOOP-230?page=all ]
Sameer Paranjpye updated HADOOP-230:
------------------------------------
Component/s: dfs
> improve syntax of the hadoop dfs command
> ----------------------------------------
>
> Key: HADOOP-230
> URL: http://issues.apache.org/jira/browse/HADOOP-230
> Project: Hadoop
> Issue Type: Improvement
> Components: dfs
> Reporter: Yoram Arnon
> Priority: Minor
>
> the hadoop dfs syntax (hadoop dfs -option value -cmd arg) is clunky: options
> must appear before the command, the command looks like just another option.
> I propose a more standard syntax:
> 1. the command (ls, mv, du etc.) always comes first
> 2. no '-' for the command
> 3. options may appear anywhere, including between the command and its
> arguments
> allowed syntax would be:
> hadoop dfs ls -dfs <dfs> /path
> hadoop dfs ls /path -dfs <dfs>
> other commands may benefit from a similar syntax change:
> hadoop job [-status] job_0002 -jt <jt>
> etc.
