Re: HBase 0.94 security configurations
I'm trying to run a test for HBase (some think we wrote, internal) on my
laptop - runs perfectly with the old versions of Hadoop, HBase and
ZooKeeeper.

After deploying the new versions and re-compiling our code, I run the test.

When I try to instantiate  "new HBaseAdmin(getConfiguration())" - where the
configuration is from HBaseTestingUtility, I get the following on the
console output:
