Subject Re: Global scheduling in the Fair Scheduler

Hi Abhishek,

You can find the in-development version of Hadoop in SVN, using the instructions at http://hadoop.apache.org/mapreduce/version_control.html.
Note that for version 0.21, the Hadoop project has been split into MapReduce, HDFS and Common,
which will make running the new version slightly trickier. There are some old instructions
about this at http://www.cloudera.com/blog/2009/07/17/the-project-split/, but I believe it's
gotten easier.

Note that you won't be able to use the 0.21 scheduler code in Hadoop 0.20 without manually
trying to port it though.
