Subject [jira] [Commented] (SPARK-22870) Dynamic allocation should allow 0 idle time
Date Fri, 22 Dec 2017 17:27:00 GMT


Felix Cheung commented on SPARK-22870:

yes there is more than the check for the value 0 as the clean up is not currently synchronous.

>                 URL:
>             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.
