Hi, Santhoosh,

Overall looks good to me now. There are still some minor issues / errors in
the design doc
- in YARN, are you sure that we persist the JobModel to coordinator stream?
I checked the code and didn't find that. The JobModel was simply generated
and served from the memory in the JobCoordinator.
- In YARN, we don't run stream processor yet. We are still running
SamzaContainer as for now.
- When describing the differences between YARN and standalone model, item 3
and 4 are not basic facts this design depends on. Instead, those seem to be
detailed design choices already. Suggest to move to requirements in the
design, not the difference between YARN and standalone model
- A further question on systems that provides VM and file system isolation
(Locker G3): in this case, even two processors are on a single physical
host, if they are in two different VMs, they can not share file system,
which means that their state stores can not be shared. And in addition, if
the system provides some common shared directory, then, what's the
locationId in such case?
