[jira] Commented: (MAPREDUCE-727) Move the bin/hadoop jar command over to bin/mapred

    [ https://issues.apache.org/jira/browse/MAPREDUCE-727?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12758814#action_12758814 ] 

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

Is there no need for a 'bin/hadoop jar' for cases where people have java code that depends on Hadoop but doesn't necessarily submit jobs? For example, a jar that requires HDFS only, but doesn't want to have to set up the various classpath stuff that common/bin/hadoop-config.sh does for you?

Certainly they can write their own wrapper script themselves that sources hadoop-config.sh out of common, but having a stock one seems somewhat useful.
