Subject [jira] [Commented] (MAPREDUCE-3366) Mapreduce component should use consistent directory structure layout as HDFS/common
Date Tue, 06 Dec 2011 00:04:40 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-3366?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13163195#comment-13163195

Eric Yang commented on MAPREDUCE-3366:

Bruno, you are right.  Thanks for catching this.  I will updated it to reflect changes in

bq. Why changing these lines:

This was done as part of merging back Hadoop into a project.  There are many configuration
files which have interconnected parts.  i.e. log4j, hadoop-metric2.properties.  It seems safer
to consolidate config files back to
HADOOP_CONF_DIR, and reduce redundancies or conflicts.  For consistency, HDFS use HADOOP_CONF_DIR
rather than
HDFS_CONF_DIR.  Yarn should follow the same pattern in my opinion.

Mahadev,  yes, this subsume MAPREDUCE-3177.
