> Optimization: Reuse Mesos offer across YARN containers

> Key: MYRIAD-103
> URL: https://issues.apache.org/jira/browse/MYRIAD-103
> Project: Myriad
> Issue Type: New Feature
> Components: Executor, Scheduler
> Reporter: Kannan Rajah
> Priority: Minor
>
> In the fine grained scheduling implementation, when YARN scheduler allocates
> a container, Myriad launches a pseudo Mesos task for it by specifying its
> resource allocation. When the container completes, a task finished update is
> sent to Mesos so that the pseudo task is stopped and its resources reclaimed.
> When there are pending tasks in the YARN scheduler’s pipeline, it would be
> beneficial to hold on to these resources and see if it can be used again.
> This avoids the overhead of giving away resources and waiting for Mesos to
> offer it back.
