What is the behavior of the default partitioner?
A
The default partitioner assigns key value pairs to reducers based on an internal random number generator.
B
The default partitioner implements a round robin strategy, shuffling the key value pairs to each reducer in turn. This ensures an even partition of the key space.
C
The default partitioner computes the hash of the key.Hash values between specific ranges are associated with different buckets, and each bucket is assigned to a specific reducer.
D
The default partitioner computes the hash of the key and divides that value modulo the number of reducers. The result determines the reducer assigned to process the key-value pair.
E
The default partitioner computes the hash of the value and takes the mod of that value with the number of reducers. The result determines the reducer assigned to process the key value pair.
