ajithme edited a comment on issue #24036: [SPARK-27036][SPARK-SQL] Cancel the 
running jobs in the background if broadcast  future timeout error occurs

   > Is it necessary to kill all these jobs? I get that they will probably fail 
without the broadcast, but, it's also possible they won't.
   
   @srowen then in this case how do we justify to the end user who will see 
that his query has failed (due to timeout) but his resource are still being 
occupied by the failed query (which may or may not eventually complete).
   
   I think killing such orphaned tasks justifies the case
