Multiple Masters within a same cluster schema

Hi,

While executed kettle job is distributed environment, we can set particular step to run on particular cluster schema. Now, all steps which are not running on cluster are executed on master. Considering heavy usage of ETL system, most of the steps of any job will be executed on master, which will create bottleneck on master. So to balance load on master, can we have multiple masters on same cluster schema? So any job can be sent to any master to execute in clustered mode.
Eventually jobs will get balanced across multiple masters and slaves. Any master can use any slave within a cluster schema.

Thanks.
