# Setup an Apache Hadoop Cluster
# 

# Read the Configuration Guide for more info:
# http://whirr.apache.org/docs/latest/configuration-guide.html

# Change the cluster name here
whirr.cluster-name=hadoop

# Change the name of cluster admin user
whirr.cluster-user=${sys:user.name}

# Change the number of machines in the cluster here
whirr.instance-templates=1 hadoop-namenode+hadoop-jobtracker,5 hadoop-datanode+hadoop-tasktracker

#
# Customise instance type or template / AMI per instance template
#

# whirr.templates.hadoop-namenode+hadoop.jobtracker.hardware-id=m1.xlarge
# whirr.templates.hadoop-datanode+hadoop.tasktracker.image-id=us-east-1/ami-da0cf8b3

#
# Uncomment out the following two lines to run CDH
#

#whirr.hadoop.install-function=install_cdh_hadoop
#whirr.hadoop.configure-function=configure_cdh_hadoop

#
# 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

#
# Or for Rackspace Cloud
#

# The size of the instance to use. See http://www.rackspacecloud.com/cloud_hosting_products/servers/faq/
# id 3: 1GB, 1 virtual core
# id 4: 2GB, 2 virtual cores
# id 5: 4GB, 2 virtual cores
# id 6: 8GB, 4 virtual cores
# id 7: 15.5GB, 4 virtual cores
# whirr.hardware-id=6
# Ubuntu 10.04 LTS Lucid
# whirr.image-id=49

#
# By default use the user system SSH keys. Override them here.
#

# whirr.private-key-file=${sys:user.home}/.ssh/id_rsa
# whirr.public-key-file=${whirr.private-key-file}.pub

#
# Expert: override Hadoop properties by setting properties with the prefix
#

# hadoop-common, hadoop-hdfs, hadoop-mapreduce to set Common, HDFS, MapReduce
# site properties, respectively. The prefix is removed by Whirr, so that for
# example, setting 
# hadoop-common.fs.trash.interval=1440
# will result in fs.trash.interval being set to 1440 in core-site.xml.

#
# Expert: specify the version of Hadoop to install.
