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: 2012-05-31 21:36:51.728 [main-SendThread(localhost.localdomain:2181)] WARN org.apache.zookeeper.client.ZooKeeperSaslClient -
