Subject RE: hbase 0.20.6 - HBaseClusterTestCase, DU, cygwin, IntelliJ - arg!
Date Wed, 19 Jan 2011 03:56:18 GMT
Hey Mark.  Sorry to hear about your troubles.

There is a new testing facility that has replaced HBaseClusterTestCase.  Check out HBaseTestingUtility.
 It's JUnit4 based.  One sample usage of it is the test TestFromClientSide.

This new one includes support for multiple DataNodes, RegionServers, and Masters.  Hopefully
that will work better for you.

As far as working in your IDE, du is part of Cygwin.  So if it's saying not found, something
in your environment (like your path) is not configured properly for Cygwin and is not finding

Hope that helps.
