Myracle commented on issue #6734: [FLINK-9455][RM] Add support for multi task slot TaskExecutors URL: https://github.com/apache/flink/pull/6734#issuecomment-571100737 @tillrohrmann Thank you for your reply. Before your change, Flink calculate pendingTaskManagerSlots(==numPendingContainerRequests * numberOfTaskSlots) in the class YarnResourceManager. Flink will only request containers from yarn when pendingTaskManagerSlots is bigger than pendingTaskManagerSlots. It means that Flink will request resources only when total requested slots can not satisfy current's requirement. There is another issue ([FLINK-9567][yarn] Before requesting new containers always check if it is required). Does FLINK-9567 resolve the same problem? What's the difference between your issue and FLINK-9567? Thank you.
