Andrew Or updated SPARK-12133:
------------------------------
Target Version/s: 2.0.0
> Support dynamic allocation in Spark Streaming
> ---------------------------------------------
>
> Key: SPARK-12133
> URL: https://issues.apache.org/jira/browse/SPARK-12133
> Project: Spark
> Issue Type: Bug
> Components: Spark Core, Streaming
> Reporter: Andrew Or
>
> Dynamic allocation is a feature that allows your cluster resources to scale
> up and down based on the workload. Currently it doesn't work well with Spark
> streaming because of several reasons:
> (1) Your executors may never be idle since they run something every N seconds
> (2) You should have at least one receiver running always
> (3) The existing heuristics don't take into account length of batch queue
> ...
> The goal of this JIRA is to provide better support for using dynamic
> allocation in streaming. The PR will revert the changes added in SPARK-10955,
> which warns against using dynamic allocation with streaming.
