apache hama on EC2 through whirr 0.8

Question

I am trying to take a look at Apache Hama and I followed the instructions at http://hama.apache.org/hama_on_clouds.html and downloaded whirr 0.8.2 but in this version there is not any hama-ec2.properties in the folder recipes, therefore i cannot try it.

Is there a reason why this file was removed in this release and there is an alternative on how to try hama through whirr on EC2.

Thanks for your help

Answer 1

You can just use the file recipes/hama.properties

The options that you care are the following:

#
# Customise instance types & AMI for Amazon EC2
#
#
# Use a specific instance type. See http://aws.amazon.com/ec2/instance-types/
whirr.hardware-id=c1.xlarge
#
# Ubuntu 10.04 LTS Lucid. See http://cloud.ubuntu.com/ami/
whirr.image-id=us-east-1/ami-35de095c
#
# You can also specify the spot instance price: http://aws.amazon.com/ec2/spot-instances/
# whirr.aws-ec2-spot-price=0.15

Also, if make sure your setup your credentials file ~/.whirr/credentials and add these lines to it.

PROVIDER=aws-ec2
IDENTITY=<YOUR AWS ACCESS KEY ID>
CREDENTIAL=<YOUR AWS SECRET ACCESS KEY>
