Anntinu Josy commented on BAHIR-104:
------------------------------------

[~fbeneventi] Thanks for reporting this issue, In mqtt.py , helper.createStream 
is called instead of helper.createPairedStream . Can you please fix this and 
add python test case and one example.

> MQTT Dstream returned by the new multi topic support API is not a pairRDD

>             Project: Bahir
>          Issue Type: Bug
>          Components: Spark Streaming Connectors
>    Affects Versions: Spark-2.1.0

> The new multi topic support API added with [BAHIR-89], when used in pyspark, 
> does not return a Dstream of <topic,message> tuples. 
> Example: 
> In pyspark, when creating a Dstream using the new API ( mqttstream = 
> MQTTUtils.createPairedStream(ssc, brokerUrl, topics) ) the expected contents 
> of mqttstream should be a collections of tuples:
> (topic,message) , (topic,message) , (topic,message) , ...
> Instead, the current content is a flattened list:
> topic, message, topic, message, topic, message, ...
> that is hard to use.
