----------------------------
Summary: Dynamically update topics list for spark kafka consumer
Key: SPARK-22561
URL: https://issues.apache.org/jira/browse/SPARK-22561
Project: Spark
Issue Type: New Feature
Components: DStreams
Affects Versions: 2.2.0, 2.1.1, 2.1.0
Reporter: Arun
The Spark Streaming application should allow to add new topic after streaming
context is intialized and DStream is started. This is very useful feature
specially when business is working multi geography or multi business units.
For example initially I have spark-kakfa consumer listening for topics:
["topic-1"."topic-2"] and after couple of days I have added new topics to kafka
["topic-3","topic-4"], now is there a way to update spark-kafka consumer topics
list and ask spark-kafka consumer to consume data for updated list of topics
without stopping sparkStreaming application or sparkStreaming context.
