Arun Suresh commented on YARN-2877:
-----------------------------------
Thanks for investigation [~leftnoteasy] and [~djp]
bq. So next time we should not update sequence of fields in trunk/branch-2,
what we need to do is to make sure fields of protos across branches has same id.
Not sure if I understand correctly, are you proposing that we should NOT
declare new fields in sequence ? for eg. if the last field index is 10 for a
struct in trunk, if we want to add a new field, we should set it as something
like 15 and not 11 ?

> This is an umbrella JIRA that proposes to extend YARN to support distributed
> scheduling. Briefly, some of the motivations for distributed scheduling are
> the following:
> 1. Improve cluster utilization by opportunistically executing tasks otherwise
> idle resources on individual machines.
> 2. Reduce allocation latency. Tasks where the scheduling time dominates
> (i.e., task execution time is much less compared to the time required for
> obtaining a container from the RM).
