Eric Yang commented on HADOOP-7518:
-----------------------------------
Hi Vinod,
Hadoop trunk supports two layouts. The original layout where common, hdfs,
mapreduce are in separated directories. The new layout which merges common,
hdfs, mapreduce into a single deploy directory. (Recommend for production
usage).
For original layout, use these command:
{noformat}
mvn package -Ptar -Dmaven.test.skip.exec=true
ant veryclean tar -Dresolvers=internal
export HADOOP_COMMON_HOME=/tmp/hadoop-common-0.23.0-SNAPSHOT
export HADOOP_HDFS_HOME=/tmp/hadoop-hdfs-0.23.0-SNAPSHOT
{noformat}
For the merged layout, use these command:
{noformat}
mvn package -Pbintar -Dmaven.test.skip.exec=true
ant veryclean binary -Dresolvers=internal
{noformat}
untar both tarballs into the same directory, i.e. /tmp/hadoop. Make sure
HADOOP_*_HOME environment are unset.
Let me know if you have any questions. Thanks.

> This is what I do:
> In common directory:
> mvn package -Pbintar -Dmaven.test.skip.exec=true
> cp target/hadoop-common-0.23.0-SNAPSHOT-bin.tar.gz ~/tmp/common/
> In hdfs directory:
> ant veryclean binary -Dresolvers=internal
> cp build/hadoop-hdfs-0.23.0-SNAPSHOT-bin.tar.gz ~/tmp/hdfs/
> Untar the tarballs, and start namenode as follows:
> {quote}
> export
> HADOOP_COMMON_HOME=~vinodkv/tmp/common/hadoop-common-0.23.0-SNAPSHOT-bin;
> export HADOOP_CONF_DIR=~vinodkv/tmp/conf;
> export HADOOP_HDFS_HOME=~vinodkv/tmp/hdfs/hadoop-hdfs-0.23.0-SNAPSHOT;
> $HADOOP_COMMON_HOME/sbin/hadoop-daemon.sh start namenode
> {quote}
> The last one simply says "Hadoop common not found." and exits.
