Shixiong Zhu resolved SPARK-21460. ---------------------------------- Resolution: Duplicate This will be addressed in SPARK-18838 > Spark dynamic allocation breaks when ListenerBus event queue runs full > ---------------------------------------------------------------------- > > Key: SPARK-21460 > URL: https://issues.apache.org/jira/browse/SPARK-21460 > Project: Spark > Issue Type: Bug > Components: Scheduler, YARN > Affects Versions: 2.0.0, 2.0.2, 2.1.0, 2.1.1, 2.2.0 > Environment: Spark 2.1 > Hadoop 2.6 > Reporter: Ruslan Dautkhanov > Priority: Critical > Labels: dynamic_allocation, performance, scheduler, yarn > > When ListenerBus event queue runs full, spark dynamic allocation stops > working - Spark fails to shrink number of executors when there are no active > jobs (Spark driver "thinks" there are active jobs since it didn't capture > when they finished) . > ps. What's worse it also makes Spark flood YARN RM with reservation requests, > so YARN preemption doesn't function properly too (we're on Spark 2.1 / Hadoop > 2.6). -- 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
