MAPREDUCE-728 could not make the code freeze deadline primarily it
couples closely with JobTracker and that there are quite a few late
patches that changed the APIs it depend on. It passed testing on
Hudson on Thursday night. All new changes I added in the latest
patch (thanks to Chris for his assist in the process) are trivial
changes to accommodate either API changes or build changes (e.g.
avro bumps up version from 1.0.0 to 1.1.0).
The patch adds a new MapReduce simulator, Mumak, as a contrib
project. it has sufficient usage to help us understand, debug,
profile, and design-proof JobTracker or scheduler.
Given the circumstances, I would like to request a vote to commit
MAPREDUCE-728 to Hadoop 0.21.
