## README.txt
Hi :)

Here are some quick instruction on running the hbase-ec.properties recipe.

1. Download Whirr 0.7.0 RC0 from here. We are going to publish this as an official release soon.

  http://people.apache.org/~asavu/whirr-0.7.0-candidate-0/whirr-0.7.0.tar.gz

2. Extract the archive

3. Save the hbase-ec.proprties recipe to a file (e.g. hbase-ec2.properties)

4. Export your AWS EC2 credentials

  export AWS_ACCESS_KEY_ID=...
  export AWS_SECRET_ACCESS_KEY=...

5. Run (don't worry if you see some SSH exception like read timeouts)

  $ ./bin/whirr launch-cluster --config hbase-ec2.properties

6. Login to the VM, become root and run "hbase shell"

7. Be happy! :)

x) Destroy the virtual machine

  $ ./bin/whirr destroy-cluster --config hbase-ec2.properties

Make sure you check Apache Whirr at http://whirr.apache.org/ and say hi! on the email list.
