> Found this while doing some testing on an internal cluster with an unusual 
> setup. We have a rack with ~20 nodes, then a few more with just a few nodes. 
> It would fail to get (# data blocks) datanodes even though there were plenty 
> of DNs on the rack with 20 DNs.
> I managed to reproduce this same issue in a unit test, stack trace like this:
> {noformat}
> java.io.IOException: File /testfile0 could only be written to 5 of the 6 
> required nodes for RS-6-3-1024k. There are 9 datanode(s) running and no 
> node(s) are excluded in this operation.

Thanks for the patch, [~andrew.wang]

One nit: why not mark {{@Before}} {{@After}} for {{setup() / {{teardown()}} in 
the test case?  Also {{cluster.waitActive()}} should be placed before 
{{setErasureCodingPolicy}} ?

+1 pending the change and jenkins.
