Subject [jira] [Commented] (MAPREDUCE-2550) bin/mapred no longer works from a source checkout
Date Wed, 08 Jun 2011 21:31:59 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-2550?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13046241#comment-13046241
] 

Eric Yang commented on MAPREDUCE-2550:
--------------------------------------

bq. Do we need the following export?
bq. +export HADOOP_PREFIX="${HADOOP_PREFIX:-$bin/..}"

This is required for "ant tar" release tarball deployment without merging the artificates
to the same directory, and used COMMON_HOME to drive environments.

> Developer may want to run hadoop without extracting tarball.  It would be nice if existing
method to run mapred scripts from source code is preserved for developers.
