One-click Hadoop WordCount on Eucalyptus FutureGrid
I. Introduction
This tutorial shows how to run a one-click Hadoop WordCount job on the Eucalyptus platform of FutureGrid.II. Prerequisite
1. FutureGrid HPC account: please apply via FutureGrid portal and request a HPC account.2. FutureGrid Eucalyptus account: please see FutureGrid Eucalyptus Tutorial for detailed instructions.
3. FutureGrid Eucalyptus credentials zip file (euca2-[username]-x509.zip) stored under user's home directory
4. Key pair created and added for use with Eucalyptus virtual machines
The following sections assume a user has created both an HPC account and a Eucalpytus account under the username of gaoxm.
III. Login to india.futuregrid.org
[gaoxm@129-79-49-98 ~]$ ssh -i .ssh/id_rsa_fg india.futuregrid.orgEnter passphrase for key '.ssh/id_rsa_fg':

[gaoxm@i136 ~]$ cd eucalyptus/
[gaoxm@i136 eucalyptus]$ ls

IV. Download and unzip the “hadoopOneClick.zip” package
[gaoxm@i136 test]$ wget http://mypage.iu.edu/~gao4/data/hadoopOneClick.zip...
[gaoxm@i136 test]$ ls
hadoopOneClick.zip
[gaoxm@i136 test]$ unzip hadoopOneClick.zip
V. Run hadoop-one-click.sh
[gaoxm@i136 test]$ cd hadoopOneClick[gaoxm@i136 hadoopOneClick]$ ls
deploy-hadoop.sh instanceIds.txt publicIps.txt stop-hadoop.sh
hadoop-one-click.sh ipHosts.txt run-hadoop-wordcount.sh terminate-instances.sh
hosts nodes.txt start-instances.sh
[gaoxm@i136 hadoopOneClick]$ chmod +x *.sh
[gaoxm@i136 hadoopOneClick]$ ./hadoop-one-click.sh -n 2 -t m1.small -i emi-D778156D -k gaoxm -p ~/eucalyptus/gaoxm.private -l http://mypage.iu.edu/~gao4/data/grexp10.txt -s http://salsahpc.indiana.edu/tutorial/apps/hadoop-0.20.203.0-for-EucaVm.tar.gz
This will run a MapReduce word-count job on a dynamically created virtual Hadoop cluster on FutureGrid. The user needs to replace the –k and –p parameter values with his/her key-pair name and private key path. For detailed usage information, try
[gaoxm@i136 hadoopOneClick]$ ./hadoop-one-click.sh -h
VI. Verify output
[gaoxm@i136 hadoopOneClick]$ ls outputs/_logs part-r-00000 _SUCCESS
[gaoxm@i136 hadoopOneClick]$ vim outputs/part-r-00000
