Re: HBase newbie
ok so I used to run hbase 0.94.4 before i realized that i had to
downgrade. my zookeeper hbase directory had the files from that version
before. once I cleaned the zookeeper directory using zkCli, master node
came up. and after that i checked and all the data directories on the
cluster are empty (there was no data in hbase). but now when i
start-hbase the master node log file just keeps saying this :

2013-02-20 15:45:39,518 INFO
