> Project: Spark
> Issue Type: Improvement
> Components: Spark Core, YARN
> Affects Versions: 1.2.0
> Reporter: Sandy Ryza
> Assignee: Sandy Ryza
> Fix For: 1.2.0

>
> Dynamic allocation tries to allocate more executors while we have pending
> tasks remaining. Our current policy can end up with more outstanding
> executor requests than needed to fulfill all the pending tasks. Capping the
> executor requests to the number of cores needed to fulfill all pending tasks
> would make dynamic allocation behavior less sensitive to settings for
> maxExecutors.
