you set "spark.streaming.concurrentJobs" larger than 1, then the
current batch could start without waiting for the previous batch (if
it is delayed), which will lead to unexpected results.

spark.streaming.concurrentJobs" larger than 1, then the current batch could
start without waiting for the previous batch (if i

For example, if "spark.streaming.concurrentJobs" is 1, and you call
DStream.count() twice. There will be two "count" Spark jobs and they will
run one by one. But if you set "spark.streaming.concurrentJobs" to 2, these
