Xuefu Zhang created SPARK-22870: ----------------------------------- Summary: Dynamic allocation should allow 0 idle time Key: SPARK-22870 URL: https://issues.apache.org/jira/browse/SPARK-22870 Project: Spark Issue Type: Improvement Components: Scheduler Affects Versions: 1.6.0 Reporter: Xuefu Zhang Priority: Minor
As discussed in SPARK-22765, with SPARK-21656, an executor will not idle out when there are pending tasks to run. When there is no task to run, an executor will die out after {{spark.dynamicAllocation.executorIdleTimeout}}, which is currently required to be greater than zero. However, for efficiency, a user should be able to specify that an executor can die out immediately w/o being required to be idle for at least 1s. This is to make {{0}} a valid value for {{spark.dynamicAllocation.executorIdleTimeout}}, and special handling such a case might be needed. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
