Subject [jira] [Commented] (MAPREDUCE-2550) bin/mapred no longer works from a source checkout
Date Wed, 08 Jun 2011 19:55:58 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-2550?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13046173#comment-13046173
] 

Todd Lipcon commented on MAPREDUCE-2550:
----------------------------------------

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

the sourcing of {{hadoop-config.sh}} should set this to point at COMMON_HOME in dev env or
the appropriate prefix in an installed env, right?

> 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.
