Alejandro Abdelnur commented on HADOOP-7563:
--------------------------------------------
Comments on '-2' patch:
Where you are doing:
{code}
if [ -d "$HADOOP_PREFIX/share/hadoop/common/lib" ]; then
CLASSPATH=${CLASSPATH}:$HADOOP_PREFIX/share/hadoop/common/lib/*;
fi
CLASSPATH=${CLASSPATH}:$HADOOP_PREFIX/share/hadoop/common/*.jar;
{code}
For the first CLASSPATH=, you have to do '/*' to prevent the shell from
resolving the wildcard. 'java' does special handing.
For the second CLASSPATH=, I don't that will be correctly resolved. There are
multiple JARs at common/ level, and some of the them are test classes and
sources. You don't want them in the classpath.
IMO, the correct fix is to change the assembly as I've pointed out before (to
have the hadoop-* artifact JAR under lib) and then do:
{code}
CLASSPATH=${CLASSPATH}:$HADOOP_PREFIX/share/hadoop/common/lib'/*';
{code}
> hadoop-config.sh setup HADOOP_HDFS_HOME and HADOOP_MAPRED_HOME incorrectly

> Components: scripts
> Affects Versions: 0.23.0
> Reporter: Eric Yang
> Assignee: Eric Yang

> 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.
