KyuubiHistoryServerPlugin usage

[hanna-liashchuk]

Hi, I found an interesting class here - KyuubiHistoryServerPlugin
But I cannot find anywhere how to use it. Any advice?

Lines 30 to 33 in 2371cc6

	* HistoryServer plugin for Kyuubi, It can be used as a plugin in SparkHistoryServer to make SparkHistoryServer UI display Kyuubi's Tab.
	* We can use it like:
	* - Copy the kyuubi-spark-sql-engine jar to $SPARK_HOME/jars and restart SparkHistoryServer.
	* - In addition, we can add kyuubi configurations to spark-defaults.conf prefixed with "spark.kyuubi.".

Ok, so I added the jar to /opt/spark/jars and set

spark.kyuubi.engine.ui.stop.enabled     true
spark.ui.killEnabled                    true

as my spark conf

I can see the tab "Kyuubi Query Engine" but I cannot see the "kill" button
I found this commit #3220

Could you please explain it? And what should I do to be able to kill spark engines in the UI?

Thanks!

The history server displays both completed and incomplete Spark jobs.
But it does not support the kill operation, so there is no need to display the kill operation in the history server.
You can find Tracking URL or application web UI in the logs.
