Keith Turner commented on ACCUMULO-708:
---------------------------------------

bq. I don't think that works. I checked out a clean copy of TRUNK, applied the 
patch, and uncommented the ACCUMULO_HOME system env setting in the pom.xml 
file. A couple of tests fail looking for the conf/accumulo-site.xml file. The 
conf/accumulo-site.xml file doesn't exist on a clean checkout.

Good catch.  If ACCUMULO_HOME is only needed by a unit test for the old 
classloader, and we are going to get rid of the old class loader, then maybe 
you could just drop that unit test before checking the code in.  Just need to 
make sure that what that old unit test does is also done by the new unit test.
