>
> Currently, each ExecutionCommandEntity stores the whole config blob. This is
> a severe duplication of data as tagged configuration information is already
> available as immutable entry.
> We need to reduce the footprint of ExecutionCommandEntity by storing only
> configuration tags. The tags can be replaced with actual configuration value
> when the command is handed off to the agent.
> We need to ensure that when Ambari is upgraded and there is a mix of
> ExecutionCommandEntity instances with and without embedded config - it works.
