Carson Wang commented on SPARK-11206:
-------------------------------------
To support SQL UI on the history server:
1. I added an onOtherEvent method to the SparkListener trait and post all SQL
related events to the same event bus.
2. Two SQL events SparkListenerSQLExecutionStart and
SparkListenerSQLExecutionEnd are defined in the sql module.
3. The new SQL events are written to event log using Jackson.
4. A new trait SparkHistoryListenerFactory is added to allow the history server
to feed events to the SQL history listener. The SQL implementation is loaded at
runtime using java.util.ServiceLoader.

> Project: Spark
> Issue Type: New Feature
> Components: SQL, Web UI
> Reporter: Carson Wang
>
> On the live web UI, there is a SQL tab which provides valuable information
> for the SQL query. But once the workload is finished, we won't see the SQL
> tab on the history server. It will be helpful if we support SQL UI on the
> history server so we can analyze it even after its execution.
