What i tried to do as a 'side fix' was like this,
eliminate [1] since it was a lazy val.
Move [2] out of the code path of the main thread i.e. let ListenerBus
thread pay the penalty of producing the physical plan for logging ( i was
coming from a performance test scenario, so it allowed me to proceed :-) ) . So
the change was that SparkListenerSQLExecutionStart only take QueryExecution as
a input parameter and not physicalPlanDescription & SparkPlanInfo . However
this cannot be the solution since SparkListenerSQLExecutionStart is a public
API already.
[3] remains.
As you might have already noticed ConsoleSink also suffers from the same
problem of [2] and these are inside Dataset.withTypedCallback/withCallback, but
it is only for Debug purposes
