Subject Re: multiple sparkcontexts and streamingcontexts
Date Mon, 02 Mar 2015 15:19:25 GMT
Sorry, I meant once the stream is started, it's not possible to create new
streams in the existing streaming context, and it's not possible to create
new streaming context if another one is already running.
So the only feasible option seemed to create new sparkcontexts for each
stream (tried using spark-jobserver for that).
