Why is the status of task inconsistent between logs and spark web ui?

I did the following operations on a rdd with 4 partitions in DStreams' foreachRDD function of my spark streaming application:



print rdd.count()
print rdd.collect()


The first statements rdd.count() is normally executed, while the second statement is always blocked by RUNNING status as the follow picture show:
enter image description here



However, when I take a look at the log, it shows that the task has finished.



18/11/09 16:45:30 INFO executor.Executor: Finished task 3.0 in stage 26.0 (TID 555). 197621638 bytes result sent via BlockManager)


What's the problem?



The spark version is pyspark==2.2.1, cluster is spark on yarn.

  • DStreams or Structured Streaming? What is the relation between the RDD and the stream?
