-----------------------------------
Instruction for running in independent layout as well as merged layout.
For independent layout:
{noformat}
mv clean package -Pdist -Dmaven.test.skip.exec=true
export
HADOOP_COMMON_HOME=`trunk/hadoop-common/target/hadoop-common-0.23.0-SNAPSHOT`
export HADOOP_HDFS_HOME=`trunk/hadoop-hdfs/target/hadoop-hdfs-0.23.0-SNAPSHOT`
# edit $HADOOP_COMMON_HOME/etc/hadoop/core-site.xml
# edit $HADOOP_HDFS_HOME/etc/hadoop/hdfs-site.xml
cd $HADOOP_HDFS_HOME
$HADOOP_HDFS_HOME/bin/hdfs namenode -format
$HADOOP_COMMON_HOME/sbin/hadoop-daemon.sh start namenode
$HADOOP_COMMON_HOME/sbin/hadoop-daemon.sh start datanode
{noformat}
For merged layout:
{noformat}
mv clean package -Pdist -Dtar -Dmaven.test.skip.exec=true
mkdir hadoop
cd hadoop
tar xv -skip-compoents=1 -f trunk/hadoop-common/target/hadoop-common*.tar.gz
trunk/hadoop-hdfs/target/hadoop-hdfs*.tar.gz
# edit etc/hadoop/core-site.xml and hdfs-site.xml
./bin/hdfs namenode -format
./sbin/hadoop-daemon.sh start namenode
./sbin/hadoop-daemon.sh start datanode
{noformat}
> hadoop-config.sh setup CLASSPATH, HADOOP_HDFS_HOME and HADOOP_MAPRED_HOME
> incorrectly

> Key: HADOOP-7563
> URL: https://issues.apache.org/jira/browse/HADOOP-7563
> Project: Hadoop Common
> Issue Type: Bug
> Components: scripts
> Affects Versions: 0.23.0
> Reporter: Eric Yang
> Assignee: Eric Yang
> Fix For: 0.23.0
>
> Attachments: HADOOP-7563-1.patch, HADOOP-7563-2.patch,
> HADOOP-7563-3.patch, HADOOP-7563-4.patch, HADOOP-7563.patch
>
>
> 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.
