arunmahadevan opened a new pull request #23912: [SPARK-21029][SS] StreamingQuery should be stopped when the SparkSession is stopped
URL: https://github.com/apache/spark/pull/23912
 
 
   ## What changes were proposed in this pull request?
   
   This patch proposes to stop the underlying streaming queries when a spark session is stopped.
   
   Without this, the streaming query continues to run and fails with exception during the next trigger.
   
   For E.g.
   
   val lines = spark.readStream.format("socket").option("host", "localhost").option("port", "9999").load()
   lines.writeStream.format("console").start
   ...
   > send some input
   ...
   spark.stop
   ...
   > send more input
   ...
   The job fails with below exception
   
   ## How was this patch tested?
   
   Tested manually. Would add unit tests once I receive feedback on the approach.
