Subject [jira] [Commented] (SPARK-18272) Test topic addition for subscribePattern on Kafka DStream and Structured Stream
Date Mon, 07 Nov 2016 21:09:58 GMT

    [ https://issues.apache.org/jira/browse/SPARK-18272?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15645460#comment-15645460

Shixiong Zhu commented on SPARK-18272:
--------------------------------------

KafkaSourceStressSuite covers this case. However, I agree we should add a separated test for
this.

> We've had reports of the following sequence
> - create subscribePattern stream that doesn't match any existing topics at the time stream
starts
> - add a topic that matches pattern
> - expect that messages from that topic show up, but they don't
> We don't seem to actually have tests that cover this case, so we should add them
