Subject [jira] [Commented] (HADOOP-7563) hadoop-config.sh setup HADOOP_HDFS_HOME and HADOOP_MAPRED_HOME incorrectly
Date Tue, 23 Aug 2011 15:41:29 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-7563?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13089546#comment-13089546

Eric Yang commented on HADOOP-7563:

The missing class in from hadoop-alfredo module.  Alejandro has made hadoop-common depends
on hadoop-alfredo, but there is no script to package hadoop-alfredo-0.23.0-SNAPSHOT.jar file
into hadoop-common-0.23.0-SNAPSHOT/share/hadoop/common.  If you manually copy it over there,
then it is possible to use the scripts to start HDFS in both merged layout as well as separated
layout using HADOOP_COMMON_HOME and HADOOP_HDFS_HOME environment variables.  Fixing alfredo
is in HADOOP-7560.  I think this jira and HDFS-2277 are ready to be committed to contain the
scope of the changes and keep things clean.

> 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.
