[jira] [Reopened] (SPARK-18193) queueStream not updated if rddQueue.add after create queueStream in Java

["Hubert Kang (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/SPARK-18193?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Hubert Kang reopened SPARK-18193:
---------------------------------

While it's inconsistent with that in QueueStream.scala.
something is pushed to the queue after ssc.start() and could be recognized successfully.

It's expected so that live data stream could be handled.
