> import time
> from pyspark import BarrierTaskContext
> n = 4
> def task(x):
> context = BarrierTaskContext.get()
> this = next(x)
> if (this % 2 == 0):
> time.sleep(10000)
> context.barrier()
> return []
> sc.setLogLevel("INFO")
> sc.parallelize(list(range(n)), n).barrier().mapPartitions(task).collect(){code}
