Install a Hama cluster using Whirr

Apache Whirr provides a Cloud-neutral way to run a properly-configured system quickly through libraries, common service API, smart defaults, and command line tool. Currently it supports various Cloud services e.g., Hadoop, HBase, Hama, Cassandra, and ZooKeeper. Let's see how it is simple to install Hama cluster using Whirr.

The following commands install Whirr and start a 5 node Hama cluster on Amazon EC2 in 5 minutes or less.

% curl -O http://apache.tt.co.kr//whirr/whirr-0.7.0/whirr-0.7.0.tar.gz
% tar zxf whirr-0.7.0.tar.gz; cd whirr-0.7.0

% export AWS_ACCESS_KEY_ID=YOUR_ID
% export AWS_SECRET_ACCESS_KEY=YOUR_SECKEY
% ssh-keygen -t rsa -P '' -f ~/.ssh/id_rsa_whirr

% bin/whirr launch-cluster --config recipes/hama-ec2.properties --private -key-file ~/.ssh/id_rsa_whirr

Upon success you should see imok echoed to the console, indicating that Hama is running.

Oh... finished. :)
