c)Specific partition in transformation

d)We cant create RDD in partition

Answer 1

Hi@ritu,

Hash Partitioning attempts to spread the data evenly across various partitions based on the key. Object.hashCode method is used to determine the partition in Spark as partition = key.hashCode () % numPartitions. According to me, option B is the right answer.

Hi, @Ritu,

option b for you, as Hash Partitioning attempts to spread the data evenly across various partitions based on the key. Object.hashCode method is used to determine the partition in Spark as partition = key.hashCode () % numPartitions.
