[SPARK-18144][SQL] logging StreamingQueryListener$QueryStartedEvent ## What changes were proposed in this pull request? The PR fixes the bug that the QueryStartedEvent is not logged The reason of the bug is that listeners in `ListenerBus` is typed as CopyOnWriteArray so that the thread calling postToAll to post QueryStartedEvent will see an empty `listeners` (stale version). In fact, we should never call postToAll() directly but call `LiveListenerBus.post()` to broadcast events @zsxwing ## How was this patch tested? ![image](https://cloud.githubusercontent.com/assets/678008/19821553/007a7d28-9d2d-11e6-9f13-49851559cdaa.png) You can merge this pull request into a Git repository by running: $ git pull https://github.com/CodingCat/spark SPARK-18144 Alternatively you can review and apply these changes as the patch at: https://github.com/apache/spark/pull/15675.patch To close this pull request, make a commit to your master/trunk branch with (at least) the following in the commit message: This closes #15675 ---- commit 5a8dc877d5d279983754919f3e44a4ba7cb3c2fa Author: CodingCat <zhunans...@gmail.com> Date: 2016-03-07T14:37:37Z improve the doc for "spark.memory.offHeap.size" commit 46788bd26737a53c5bc76089012ecb2515f0260b Author: CodingCat <zhunans...@gmail.com> Date: 2016-03-07T19:00:16Z fix commit 766c67d4d1609782bf7558a2b7c742df72bff620 Author: CodingCat <zhunans...@gmail.com> Date: 2016-10-28T20:20:47Z postToAll has to be called in the same thread ---- --- If your project is set up for it, you can reply to this email and have your reply appear on GitHub as well.
