Apache Spark commented on SPARK-19755: -------------------------------------- User 'IgorBerman' has created a pull request for this issue: https://github.com/apache/spark/pull/20640 > Blacklist is always active for MesosCoarseGrainedSchedulerBackend. As result > - scheduler cannot create an executor after some time. > ----------------------------------------------------------------------------------------------------------------------------------- > > Key: SPARK-19755 > URL: https://issues.apache.org/jira/browse/SPARK-19755 > Project: Spark > Issue Type: Bug > Components: Mesos, Scheduler > Affects Versions: 2.1.0 > Environment: mesos, marathon, docker - driver and executors are > dockerized. > Reporter: Timur Abakumov > Priority: Major > > When for some reason task fails - MesosCoarseGrainedSchedulerBackend > increased failure counter for a slave where that task was running. > When counter is >=2 (MAX_SLAVE_FAILURES) mesos slave is excluded. > Over time scheduler cannot create a new executor - every slave is is in the > blacklist. Task failure not necessary related to host health- especially for > long running stream apps. > If accepted as a bug: possible solution is to use: spark.blacklist.enabled to > make that functionality optional and if it make sense MAX_SLAVE_FAILURES > also can be configurable. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
