Hello Sebastian, Alejandro, Andrew,

Referring to the discussion on RB: https://reviews.apache.org/r/43948
<https://reviews.apache.org/r/43948/#review120537>, it appears that while
deploying clusters using Blueprints, RCO is not honored. Please confirm if
this understanding is correct.

While running internal test suites for HAWQ, we deploy the clusters using
BP, and we need a specific order in which the HAWQ components must be
initialized / started.

"HAWQ Standby" component should be initialized after "HAWQ Master"
component as it has to copy the contents from HAWQ Master. However, since
RCO is not honored, we often come across issues as HAWQ Standby start /
initialization before HAWQ Master.

Could you please let us know if there any work already going on for
bringing in RCO dependency for Blueprints, if not is there any other
alternative which can be used to enforce the dependency locally, or
something else which you suggest.

Thanks,
Bhuvnesh Chaudhary
