> How i must build my code with repartitional and persist\coalesce for to
> nodes not crashes?
> I tried to rebuild the program in different ways, transferring repartitioning
> and saving in memory / disk inside the loop, installed a large number of
> partitions - 200.
> The program either hangs on the “repartition” stage or crashes into error
> code 143 (outOfMemory), throwing a stackOverflowError in a strange way.
