onursatici opened a new pull request #24625: [SPARK-27744][SQL] preserve spark properties on async subquery tasks
URL: https://github.com/apache/spark/pull/24625
 
 
   ## What changes were proposed in this pull request?
   
   Add a new future helper method that copies over spark properties before submitting to a new thread, and sets the original properties back on exit. SubqueryExec now uses this method to create futures. Any task that is submitted to its thread pool will now use the spark properties of the submitting thread, instead of the spark properties that were on the thread pool worker thread
   
   ## How was this patch tested?
   
   Added a test, which fails with current master but passes with this patch
