improve syntax of the hadoop dfs command
-----------------------------------------
Key: HADOOP-230
URL: http://issues.apache.org/jira/browse/HADOOP-230
Project: Hadoop
Type: Improvement
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 job [-status] job_0002 -jt <jt>
etc.
