------------------------------------
Summary: Speed up task serialization in standalone mode
Key: SPARK-7795
URL: https://issues.apache.org/jira/browse/SPARK-7795
Project: Spark
Issue Type: Improvement
Components: Spark Core
Affects Versions: 1.3.1
Reporter: Akshat Aranya
My experiments with scheduling very short tasks in standalone cluster mode
indicated that a significant amount of time was being spent in scheduling the
tasks (>500ms for 256 tasks). I found that most of the time was being spent in
creating a new instance of serializer for each task. Changing this to just one
serializer brought down the scheduling time to 8ms.
