If these patches are going to be included with 1.4.4 or 1.4.5, I would like
to see the following test run using CDH4 on at least a 5 node cluster.
 More nodes would be better.

  * unit test
  * Functional test
  * 24 hr Continuous ingest + verification
  * 24 hr Continuous ingest + verification + agitation
  * 24 hr Random walk
  * 24 hr Random walk + agitation

I may be able to assist with this, but I can not make any promises.

Great.  I think this would be a good patch for 1.4.   I assume that if a
user stays with Hadoop 1 there are no dependency changes?
