Description

In my streaming job (that uses actorStreams) I'm stopping the SparkStreaming context via ssc.stop(stopSparkContext = true, stopGracefully = true). Sometimes this leads to the Spark master being in a permanent error state that just displays an error page instead of the UI.

The following is being logged when trying to access the master UI:
