             Project: Flink
          Issue Type: Sub-task
          Components: Runtime / Network

            Reporter: Yingjie Cao
             Fix For: 1.15.0, 1.13.6, 1.14.4


For the current sort-shuffle implementation, the different lock order in SortMergeSubpartitionReader and SortMergeResultPartitionReadScheduler can cause deadlock. To solve the problem, we can move buffer recycle in SortMergeSubpartitionReader out of the lock.
