   ### What happened?
   
   **Issue**
   If you try to read any file line by line using TextIO.read() in Spark 
cluster, SparkRunner runs the tasks in multiple executors. But when you just 
switch to SparkStructuredStreamingRunner, it runs only in one executor. The 
distribution behavior should should remain the same even if the underlying API 
is changed from RDD to Dataset.
