Wenchen Fan 9690eba16e [SPARK-25680][SQL] SQL execution listener shouldn't happen on execution thread ... ## What changes were proposed in this pull request? The SQL execution listener framework was created from scratch(see https://github.com/apache/spark/pull/9078). It didn't leverage what we already have in the spark listener framework, and one major problem is, the listener runs on the spark execution thread, which means a bad listener can block spark's query processing. This PR re-implements the SQL execution listener framework. Now `ExecutionListenerManager` is just a normal spark listener, which watches the `SparkListenerSQLExecutionEnd` events and post events to the user-provided SQL execution listeners. ## How was this patch tested? existing tests. Closes #22674 from cloud-fan/listener. Authored-by: Wenchen Fan <wenchen@databricks.com> Signed-off-by: Wenchen Fan <wenchen@databricks.com>		2018-10-17 16:06:07 +08:00
