[jira] [Created] (SPARK-7533) Decrease spacing between AM-RM
heartbeats.
Sandy Ryza created SPARK-7533:
---------------------------------
Summary: Decrease spacing between AM-RM heartbeats.
Key: SPARK-7533
URL: https://issues.apache.org/jira/browse/SPARK-7533
Project: Spark
Issue Type: Improvement
Components: YARN
Affects Versions: 1.3.1
Reporter: Sandy Ryza
The current default of spark.yarn.scheduler.heartbeat.interval-ms is 5 seconds. This is really long. For reference, the MR equivalent is 1 second.
To avoid noise and unnecessary communication, we could have a fast rate for when we're waiting for executors and a slow rate for when we're just heartbeating.
