[jira] [Created] (BAHIR-164) Spark Streaming with MQTT fails with Spark 2.3.0

Jussi-Pekka Partanen created BAHIR-164:
------------------------------------------

             Summary: Spark Streaming with MQTT fails with Spark 2.3.0
                 Key: BAHIR-164
                 URL: https://issues.apache.org/jira/browse/BAHIR-164
             Project: Bahir
          Issue Type: Bug
          Components: Spark Streaming Connectors
    Affects Versions: Spark-2.2.0
            Reporter: Jussi-Pekka Partanen


Currently I’m not able to use latest Spark 2.3.0 release together with Bahir, but getting the following error:
 
_java.lang.AssertionError: assertion failed: DataFrame returned by getBatch from org.apache.bahir.sql.streaming.mqtt.MQTTTextStreamSource@66847d45 did not have isStreaming=true_
 
org/apache/bahir/sql/streaming/mqtt/MQTTStreamSource.scala line 164 seems to be causing the issue, i.e. it’s returning a normal dataframe instead of streaming dataframe.
 
There seems to be discussion about the same topic, but on stream source for Kafka: https://lists.apache.org/thread.html/015f2fbe9fbeafb86214a969a2d883a4898621189a86f21a4c6fbb75@%3Cdev.spark.apache.org%3E
