ADAPTIVE PARALLEL DATA PROCESSING
First Claim
1. A computer program product comprising:
- a computer readable storage medium having computer readable program code embodied therewith, the computer readable program code comprising;
computer readable program code configured to provide a map phase in which at least one map function is applied in parallel on different partitions of input data at different mappers in a parallel data processing system;
computer readable program code configured to provide a communication channel between mappers using a distributed meta-data store, wherein said map phase comprises mapper data processing adapted responsive to communication with said distributed meta-data store; and
computer readable program code configured to provide data accessible by at least one reduce phase node in which at least one reduce function is applied.
