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
