9. Prerequisites Install VirtualBox on your laptop, download and import a prepackaged image Install VirtualBox on your laptop, download and import a prepackaged image Setup FutureGrid Eucalyptus environment Make sure you setup the shared folder between host and guest machine correctly # login to FutureGrid India Headnode i136 $ ssh -i ~/fg_private_key.pem johnny@india.futuregrid.orgjohnny@india.futuregrid.org ~/fg_private_key.pem have to be replaced to your own private key file name

10. About Pre-packaged Image It has the following software installed and configured under /root/software/: – Java JDK – Chef – Hadoop – Twister and ActiveMQ – Hbase – Pig – salsaDPI (/root/salsaDPI/)

11. Important Notes If you have activemq.log and kahadb in directory /root/software/apache-activemq-5.4.2/, please remove them. Otherwise, it will cause errors when running sandbox Twister applications. $ cd /root/software/apache-activemq-5.4.2/ $ ls activemq.log kahadb $ rm -rf activemq.log kahadb

12. Examples Example 1: Sandbox Hadoop WordCount Example 2: Cloud Twister WordCount Goals – Learn and modify SalsaDPI json configuration file – Execute SalsaDPI java executable with passing the configuration file – http://salsahpc.indiana.edu/ScienceCloud/handso n1_chef_sandbox.html http://salsahpc.indiana.edu/ScienceCloud/handso n1_chef_sandbox.html * Json metadata format example : http://json.org/example.html

13. Step 1. Open the Conf. File Locate and open the configuration file. – /root/salsaDPI/sandbox/templates/sandbox _hadoopTemplate.json – /root/salsaDPI/sandbox/templates/sandbox _twisterTemplate.json

14. Step 2. Modify Conf. File 'applicationParameters': { 'applicationType':'Hadoop', 'localPathOfProgramBinary':'/root/salsaDPI/apps/hadoopWordCount.jar', 'localPathOfProgramInput':'/root/salsaDPI/input/hadoopWordCountInput.txt', 'localPathOfBinaryDependency':'', 'programExecuteLocation':'', 'programArgs':'bin/hadoop jar #_JAR_# #_HDFS_INPUTDIR_# #_HDFS_OUTPUTDIR_#' }
