Allow user to specify spot instance price per instance template group
---------------------------------------------------------------------
Key: WHIRR-461
URL: https://issues.apache.org/jira/browse/WHIRR-461
Project: Whirr
Issue Type: Improvement
Reporter: Andrei Savu
Assignee: Andrei Savu
Fix For: 0.8.0
A natural improvement on top of WHIRR-332 is to allow the user to specify the
spot instance price per instance template group.
Proposed syntax:
{noformat}
whirr.templates.role1+role2.aws-ec2-spot-price=0.23
{noformat}
Using this feature we can have a Hadoop cluster that has both regular and spot
instance like this:
{noformat}
whirr.cluster-name=hadoop-on-ec2
whirr.instance-templates=1 hadoop-namenode+hadoop-jobtracker, 3
hadoop-datanode+hadoop-jobtracker, 7 hadoop-datanode+hadoop-jobtracker+noop
# user a large instance for the namenode as needed
whirr.templates.hadoop-namenode+hadoop-jobtracker.hardware-id=c1.xlarge
# regular smaller instance for a few data nodes
whirr.templates.hadoop-datanode+hadoop-jobtracker.hardware-id=m1.large
# and spot instances for the rest of the datanodes
whirr.templats.hadoop-datanode+hadoop-tasktracker+noop.aws-ec2-spot-price=0.32
{noformat}
