I am doing a spark Structured to read some data from Topic. Irrespective of the data present in the topic I want to trigger another spark job from the streaming job. Once message is coming My streaming is able to read and trigger a spark job(hardcoded) but when the kafka message produce another message after 1 hour,it should read and retrigger that job(which is hardcoded as a child job inside streaming job).but this is not happening. Streaming job is nt reading . We are using spark 2.2 in hortonworks cluster.
