We are trying to migrate from a local hbase/hadoop installation to mapR. When we startup our application that is using the stumpleupon API (ZK 3.2.2) we see the following in our logs

    2012-07-12 09:38:41,656 [main] INFO  org.apache.zookeeper.ZooKeeper - Initiating client connection, connectString= sessionTimeout=60000 watcher=hconnection

The port is listening on the mapR machine

     telnet 2181
     Connected to celertech-dev-mapr.
