7 A Peer-to-Peer Framework for Supporting MapReduce Applications in Dynamic Cloud 119
by edge peers to locate the resources of interest. Peers sharing a common set of interests are organized into a peer group. To send messages to each other, JXTA peers use asynchronous communication mechanisms called pipes. Pipes can be either point-to-point or multicast, so as to support a wide range of communication schemes. All resources (peers, services, etc.) are described by advertisements that are published within the peer group for resource-discovery purposes.
In the following, we briefly describe how the JXTA components are used in the P2P-MapReduce system to implement basic mechanisms for resource discovery, network maintenance, job submission, and failure recovery. Then, we describe the state diagram that steers the behavior of a generic node and the software modules provided by each node in a P2P-MapReduce network.
7.3.2.1 Basic Mechanisms
Resource Discovery
All master and slave nodes in the P2P-MapReduce system belong to a single JXTA peer group called MapReduceGroup. Most of these nodes are edge peers, but some of them also act as rendezvous peers, in a way that is transparent to the users. Each node exposes its features by publishing an advertisement containing basic information, such as its Role and WorkloadIndex.
An edge peer publishes its advertisement in a local cache and sends some keys identifying that advertisement to a rendezvous peer. The rendezvous peer uses those keys to index the advertisement in a distributed hash table called Shared Resource Distributed Index (SRDI), managed by all the rendezvous peers of MapReduceGroup. Queries for a given type of resource (e.g., master nodes) are submitted to the JXTA Discovery Services that uses SRDI to locate all the resources of that type without flooding the entire network.
Note that M-net and S-net, represented in Fig. 7.2, are “logical” networks in the sense that queries to M-net (or S-net) are actually submitted to the whole MapReduceGroup, but restricted to nodes having the attribute Role set to “Master” (or “Slave”) using the SRDI mechanisms.
Network Maintenance
Network maintenance is carried out cooperatively by all nodes on the basis of their role. The maintenance task of each slave node is to periodically check the existence of at least one master in the network. In case no masters are found, the slave promotes itself to the master role. In this way, the first node joining the network always assumes the master role. The same happens to the last node remaining into the network.
The maintenance task of master nodes is to ensure the existence of a given percentage p of masters on the total number of nodes. This task is performed periodically by one master only (referred to as coordinator), which is elected for this purpose among
