We use `initializeShuffleManager` in driver/executor after classpath has been fixed up (see more below in comment for `shuffleBlockGetterFn`). ```suggestion private[spark] def initiailzeShuffleManager(): Unit = { Preconditions.checkState(null == _shuffleManager, "Shuffle manager already initialized to %s", _shuffleManager) _shuffleManager = ShuffleManager.create(conf, executorId == SparkContext.DRIVER_IDENTIFIER) } ``` -- This is an automated message from the Apache Git Service.
