Also fix this test like: ``` test("share messages with allGather() call") { val conf = new SparkConf() .setMaster("local-cluster[4, 1, 1024]") .setAppName("test-cluster") sc = new SparkContext(conf) val rdd = sc.makeRDD(1 to 4, 4) val rdd2 = rdd.barrier().mapPartitions { it => val context = BarrierTaskContext.get() // Sleep for a random time before global sync. Thread.sleep(Random.nextInt(1000)) // Pass partitionId message in val message: String = context.partitionId().toString val messages: Array[String] = context.allGather(message) Iterator.single(messages.toList) } // Take a sorted list of all the partitionId messages val messages_list = rdd2.collect() assert (messages_list.length === 4) for (messages <- messages_list) { assert (messages === (0 until 4).map(_.toString).toList) } } ``` ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
