Hi all, For research reasons I would like to run Hadoop MapReduce on a heterogeneous EC2 cluster placing 5 datanodes+tasktrackers on m1.medium and 5 datanodes+tasktrackers on m1.large instances.
I know that in https://issues.apache.org/jira/browse/WHIRR-332 some work was done towards using different instances depending on a role. But in my case I need to use different instances for the same role. Is this level of customization supported? If not, does the whole architecture supports possible introduction of this feature? -- Best regards Andrii Vozniuk
