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. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscribe@spark.apache.org For additional commands, e-mail: issues-help@spark.apache.org
