-------------------------------------

[~tdas] Now I'm not clear about how to deal with only some of the receivers had broken down, should we shutdown the StreamingContext ? Or ignore this and leave the alive receivers still running

> Streaming consider the receiver as a common spark job, thus if an error occurs in the receiver's  logical(after 4 times(default) retries ), streaming will no longer get any data but the streaming job is still running. 
> A general scenario is that: we config the `spark.streaming.receiver.writeAheadLog.enable` as true to use the `ReliableKafkaReceiver` but do not set the checkpoint dir. Then the receiver will soon be shut down but the streaming is alive.
