> Using HDFS for saving message for mqtt source

> Key: BAHIR-183
> URL: https://issues.apache.org/jira/browse/BAHIR-183
> Project: Bahir
> Issue Type: Improvement
> Components: Spark Structured Streaming Connectors
> Affects Versions: Spark-2.2.0
> Reporter: Wang Yanlin
> Priority: Major
> Fix For: Spark-2.2.1
>
>
> Currently in spark-sql-streaming-mqtt, the received mqtt message is saved in
> a local file by driver, this will have the risks of losing data for cluster
> mode when application master failover occurs. So saving in-coming mqtt
> messages using a director in checkpoint will solve this problem.
