Subject [jira] [Commented] (HADOOP-7563) hadoop-config.sh setup HADOOP_HDFS_HOME and HADOOP_MAPRED_HOME incorrectly
Date Tue, 23 Aug 2011 15:49:29 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-7563?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13089550#comment-13089550

Alejandro Abdelnur commented on HADOOP-7563:

I think I know the problem, the assembly is excluding hadoop-* JARs from going into lib. 

Currently Hadoop JARs are special and they don't go under lib/, there was a discussion going
on in the alias a while back on this.

Given that the dist is created in a complete different way now with Maven, and running from
source is a bit different, I think the cleanest way (for assembly and from scripts) would
be to put all JARs (Hadoop included) under lib/. 

The release-notes would clearly state this change.

I'll verify this later this morning and I'll follow up with a JIRA.

> HADOOP_HDFS_HOME and HADOOP_MAPRED_HOME was set to HADOOP_PREFIX/share/hadoop/hdfs and
HADOOP_PREFIX/share/hadoop/mapreduce.  This setup confuses the location of hdfs and mapred
scripts.  Instead the script should look for hdfs and mapred script in HADOOP_PREFIX/bin.
