Subject [jira] [Commented] (MAPREDUCE-3000) Move /mapred to /user/mapred for Hadoop 0.20.205
Date Wed, 14 Sep 2011 17:25:11 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-3000?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13104686#comment-13104686
] 

Eli Collins commented on MAPREDUCE-3000:
----------------------------------------

The default has been ${hadoop.tmp.dir}/mapred/system (/user/mapred) for a long time. Per Allen,
why does it make sense to put the mapred system dir in a home directory? That doesn't make
sense to me either.

> /mapred directory should be default to /user/mapred.  Owen request this to be changed
for RPM deployment in 0.20.204.  This is a regression in 0.20.205 that /user/mapred is configured
back to /mapred.
