SuYan commented on SPARK-15815: ------------------------------- Can someone tell me about the reason for "Won't fix"? > Hang while enable blacklistExecutor and DynamicExecutorAllocator > ----------------------------------------------------------------- > > Key: SPARK-15815 > URL: https://issues.apache.org/jira/browse/SPARK-15815 > Project: Spark > Issue Type: Bug > Components: Scheduler, Spark Core > Affects Versions: 1.6.1 > Reporter: SuYan > Priority: Minor > > Enable BlacklistExecutor with some time large than 120s and enabled > DynamicAllocate with minExecutors = 0 > 1. Assume there only left 1 task running in Executor A, and other Executor > are all timeout. > 2. the task failed, so task will not scheduled in current Executor A due to > enable blacklistTime. > 3. For ExecutorAllocateManager, it always request targetNumExecutor=1 > executors, due to we already have executor A, so the oldTargetNumExecutor == > targetNumExecutor = 1, so will never add more Executors...even if Executor A > was timeout. it became endless request delta=0 executors. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
