Subject Re: [SparkStreaming] Is it possible to delay the start of some DStream in the application?
Date Sun, 17 May 2015 15:28:59 GMT
Why not just trigger your batch job with that event?

If you really need streaming, then you can create a custom receiver and
make the receiver sleep till the event has happened. That will obviously
run your streaming pipelines without having any data to process.
