-----------------------------------
Thanks [~hermansc], I noticed that my previous understanding may not be
correct. Let me do some further investigation and see what I could do to update
the pull request.
> Flume streaming should respect maxRate (and backpressure)
> ---------------------------------------------------------
>
> Key: SPARK-14531
> URL: https://issues.apache.org/jira/browse/SPARK-14531
> Project: Spark
> Issue Type: Bug
> Components: Streaming
> Affects Versions: 1.6.1
> Reporter: Herman Schistad
> Priority: Minor
>
> As far as I can understand the FlumeUtils.createPollingStream(...) ignores
> key spark streaming configuration options such as:
> spark.streaming.backpressure.enabled
> spark.streaming.receiver.maxRate
> ...
> I might just be mistaken, but since the DEFAULT_POLLING_BATCH_SIZE is set to
> 1000 in the source code itself, then I presume it should use the variables
> above instead.
> *Relevant code:*
> https://github.com/apache/spark/blob/master/external/flume/src/main/scala/org/apache/spark/streaming/flume/FlumeUtils.scala
