Roman Shaposhnik commented on HADOOP-9917:
------------------------------------------
It simply means that users are encouraged to start using 'mapred' command for
manipulating their MR jobs instead of a top level 'hadoop' command. Perhaps
just adding quotes (like I did in a preceding sentence) around 'mapred' to make
it standout as a name of a command to use would do? Or mapred(1)?

> When I am killing a job like this
> hadoop job -kill <jobid>
> I am getting a cryptic warning, which I don't really understand:
> DEPRECATED: Use of this script to execute mapred command is deprecated.
> Instead use the mapred command for it.
> I fail parsing this and I believe many others will do too. Please make this
> warning clearer.
