Performance Analysis

We describe in this section the infrastructure we used for testing, the parameters we considered as relevant when running the tests and the results we obtained.

Testing Infrastructure

We have used a maximum of four computers from ED202, running Ubuntu 8.04, Hadoop 0.20.1, Pig 0.5.0 and mpich2. As the main idea of a distributed system is to use commodity hardware, we did not consider the nodes' hardware structure as relevant.

The first test scenario uses two nodes. For the Hadoop Framework, one of them is master, having in the same time master attributions (namenode - keeps the structure of the file system, jobTracker - keeps track of the jobs' execution), taskTracker - keeps track of the tasks


  • High performance and scalability
  • Portability
  • Productivity is not a principal objective for MPI!!
