igreenfield commented on issue #1931: [SPARK-3015] Block on cleaning tasks to 
prevent Akka timeouts
URL: https://github.com/apache/spark/pull/1931#issuecomment-483139476
 
 
   @andrewor14 
   I see in the code:
   
   /**
      * Whether the cleaning thread will block on cleanup tasks (other than 
shuffle, which
      * is controlled by the `spark.cleaner.referenceTracking.blocking.shuffle` 
parameter).
      *
      * Due to SPARK-3015, this is set to true by default. This is intended to 
be only a temporary
      * workaround for the issue, which is ultimately caused by the way the 
BlockManager endpoints
      * issue inter-dependent blocking RPC messages to each other at high 
frequencies. This happens,
      * for instance, when the driver performs a GC and cleans up all broadcast 
blocks that are no
      * longer in scope.
      */
   
   does that still needed?
