spark版本：2.3
spark流应用程序从hdfs路径流式传输

Dataset<Row> lines = spark
  .readStream()
  .format("text")
  .load("path");

经过一些数据转换后，对于一个文件，作业应该处于succeeded状态。
job listner是为job end添加的，它在触发文件时移动文件。

@Override
public void onJobENd(SparkListenerJobEnd jobEnd) {
// Move source file to some other location which is finished processing. 
}

文件成功移动到另一个位置。但同时（确切的时间戳）spark抛出以下文件not found exception。这是随机发生的，无法复制。但是经常发生
即使特定作业已结束，spark仍以某种方式引用该文件。
如何确保作业结束后spark未引用文件并避免此文件找不到问题
我可以在这里找到

DAGScheduler does cleanUpAfterSchedulerStop, handleTaskCompletion, failJobAndIndependentStages, and markMapStageJobAsFinished.

同样的问题，不同的方法
