Arun C Murthy commented on MAPREDUCE-727:
-----------------------------------------
bq. Arun, do you mean we would add more functionality to -submit, i.e. to
respect a jar also?
Yes, and leave 'bin/hadoop jar' as is.
bq. Going a bit off-topic from this JIRA, I think a very useful mapred command
line would be: mapred job -submit -jar foo.jar -mapper [...]
You can already do that with -Dmapred.map.tasks=5 -Dmapred.reduce.tasks=5 and
so on. Are you proposing we replace them with hadoop_streaming style parameters
such as -mapper, -reducer and so on? The reason that is a problem is that we
will have 1:1 correspondence between those switches and config knobs anyway...
> Move the bin/hadoop jar command over to bin/mapred
