Requirements for Context-aware MapReduce on Pervasive Grids
Résumé
PER-MARE project aims at adapting MapReduce distribution to pervasive grids. Such adaptation includes implementing context-awareness capabilities into Hadoop distribution. The main purpose of this deliverable is to analyze the requirements for including such support for context-awareness on Hadoop. Context-awareness can be defined as the ability of a system to adapt its operations to the current context, aiming at increasing usability and effectiveness by taking environmental context into account. Such environment corresponds, in the case of PER-MARE project, to a pervasive grid environment and its dynamic resources. It is then important to analyze such environment and its main characteristics, as well as the impact of observing such environment on Hadoop distribution. Indeed, performance of MapReduce applications should not be negatively impacted by context- awareness capabilities, which makes important to carefully consider context-awareness needs and implications of Hadoop distribution and on MapReduce application over pervasive grids. This deliverable intends to point out a set of requirements for context-aware support on PER-MARE project. These requirements will guide subsequent proposals on this domain.
