Abstract:

In the existing MapReduce framework, the single master is the performance bottleneck. As a result, the size of the cluster is limited. In order to break the bottleneck, a multimaster framework is proposed in this paper. The implementation is based on Apache Hadoop MapReduce. The main framework and signaling system are redesigned to sustain more than one master. Meanwhile a doublemaster hot backup scheme is designed to solve single master failure, so that the new framework is able to reduce the impact of master failure.

Key words: cloud computing, mapreduce framework, multi-master, performance bottleneck
