Sean Owen reassigned SPARK-22870: --------------------------------- Assignee: Yuming Wang > 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 > Assignee: Yuming Wang > Priority: Minor > Fix For: 2.3.0 > > > 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
