>
> I removed hadoop-jobtracker and hadoop-tasktracker from
> whirr.instance-templates in hbase-ec2.properties.
> Then I got the following error when trying to start a cluster.
> Am I doing anything wrong by removing the tracker from instance templates?
> Or is this an issue or not?
> If it is not an issue, am I be able to start hbase without starting the
> jobtracker and tasktracker? What is the right way to do it?
