It's responsibilities varies > from managing job submission process, compute the input splits, schedule > the tasks to the slave nodes (TaskTrackers) and monitor their health. > In some environments, like the IBM and Google's Internet-scale com- > puting initiative, there is the need for high-availability, and performances > becomes a secondary issue. In this environments, having a system with > a Single Point of Failure (such as Hadoop's single JobTracker) is a major > concern. > My proposal is to provide a redundant version of Hadoop by adding > support for multiple replicated JobTrackers. This design can be approached > in many dierent ways. > In the document at: > http://sites.google.com/site/hadoopthesis/Home/FaultTolerantHadoop.pdf?attredirects=0 > I wrote an overview of the problem and some approaches to solve it. > I post this to the community to gather feedback on the best way to proceed in > my work. > Thank you! -- This message is automatically generated by JIRA.
