org.apache.spark
A org.apache.spark.Partitioner that implements hash-based partitioning using Java's Object.hashCode.
Object.hashCode
Java arrays have hashCodes that are based on the arrays' identities rather than their contents, so attempting to partition an RDD[Array[_]] or RDD[(Array[_], _)] using a HashPartitioner will produce an unexpected or incorrect result.
