I fail to inert three words in redis by using spark, and always get java.lang.ArrayIndexOutOfBoundsException: 0. My spark version is 2.4 and spark-redis_2.11.

val wc = sc.parallelize(List(
("hello", "1")
))
sc.toRedisHASH(wc, "map1")
sc.toRedisHASH(wc, "map2")
sc.toRedisHASH(wc, "map3")

I find the problem, our clusters lead to spark-redis cannot connect success, thank you so much.
