Hi Manu, with Flip-6 we will be able to support stricter application isolation by starting for each job a dedicated JobManager which will execute its tasks on TM reserved solely for this job. But at the same time we will continue supporting the multi-tenant cluster mode where tasks belonging to multiple jobs share the same set of TMs and, thus, might share information between them.
