    • Enhance OutputCommitter and FileOutputCommitter to allow for recover of tasks across job restart.

    Description

      In MR AM recovers from a crash, it only reruns the non completed tasks. The completed tasks (along with their output, if any) needs to be recovered from the previous life. This would require some changes in OutputCommitter.
