Summary: 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.
