Subject [jira] Commented: (MAPREDUCE-727) Move the bin/hadoop jar command over to bin/mapred
Date Wed, 11 Nov 2009 08:10:39 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-727?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12776357#action_12776357
] 

Todd Lipcon commented on MAPREDUCE-727:
---------------------------------------

bq. Couldn't applications just use 'bin/hadoop -classpath' to get the required classpath rather
that 'bin/hadoop jar'?

Yea, but then you lose out on the other goodies like java.library.path, HADOOP_ROOT_LOGGER
settings, etc.

bq. OTOH this might a good opportunity to deprecate the 'jar' command in favour 'job -submit'
command i.e. 'bin/hadoop job -submit ...'?

What about jars that submit multiple jobs? If there were a one-to-one correspondence there
that would make more sense to me.

> Currently 'bin/hadoop jar' is used to submit jobs, we should move it over to bin/mapred.
