Kim Yong Hwan commented on SPARK-16599:
---------------------------------------
I have same problem too. I installed spark-2.1.0-bin-hadoop2.7 on Mac.
My example code is below, very simple. But sometimes
"java.util.NoSuchElementException: None.get" was throwned.
val nums = 1 to 300000
val powerfulRdd = sc.parallelize(nums)
powerfulRdd.filter(_ % 2 == 0).collect()
Error is below.
