Apache Spark reassigned SPARK-7533:
-----------------------------------

    Assignee:     (was: Apache Spark)

> 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.
