Hello, If anyone is interested, here are my notes on how to build trunk on bare bones AWS EC2 instance.
1. Create a XL 64-bit AWS EC2 instance (anything smaller fails due to lack of RAM) 2. SSH to EC2 instance 3. sudo useradd -u 1000 hadoop 4. sudo yum install svn gcc.x86_64 gcc-c++.x86_64 libtool.x86_64 make.x86_64 automake.noarch autoconf.noarch java-1.6.0-openjdk-devel.x86_64 zlib-devel.x86_64 5. set JAVA_HOME in vi /etc/profile.d/aws-apitools-common.sh to /usr/lib/jvm/java (if you don't the native components will not build due to using an incorrect JAVA_HOME even if you set evn JAVA_HOME) 6. reboot 7. login 8. su hadoop 9. sudo mkdir /data 10. sudo chown -R hadoop:hadoop /data 11. cd /data 12. wget http://apache.petsads.us//forrest/apache-forrest-0.9.tar.gz 13. wget http://mirror.cc.columbia.edu/pub/software/apache//maven/binaries/apache-maven-3.0.3-bin.tar.gz 14. wget http://protobuf.googlecode.com/files/protobuf-2.4.1.tar.gz 15. wget http://superb-sea2.dl.sourceforge.net/project/findbugs/findbugs/2.0.0/findbugs-2.0.0.tar.gz 16. gunzip *.gz 17. tar xf apache-forrest-0.9.tar 18. tar xf apache-maven-3.0.3-bin.tar 19. tar xf findbugs-2.0.0.tar 20. tar xf protobuf-2.4.1.tar 21. export FORREST_HOME=/data/apache-forrest-0.9 22. export MAVEN_HOME=/data/apache-maven-3.0.3 23. export FINDBUGS_HOME=/data/findbugs-2.0.0 24. cd protobuf-2.4.1 25. ./configure 26. make 27. sudo make install 28. cd .. 29. export PATH=/usr/local/bin/:/data/apache-maven-3.0.3/bin/:/data/apache-forrest-0.9/bin/:/data/findbugs-2.0.0/bin/:$PATH 30. svn checkout http://svn.apache.org/repos/asf/hadoop/common/trunk/hadoop-trunk 31. cd hadoop-trunk 32. mvn package -Pdist,native,docs -DskipTests -Dtar I have not actually used the constructed tar yet, but wanted to share my notes. I did notice two things missing (compared to the regular pre-yarn releases), there is no conf directory, nor example jars. I know trunk is being worked on but I am not sure what the plan is there (or if I simply missed something.) If you have any comments, questions, or advice I love to here it. Kindest regards. Ron
