Unable to connect to remote hbase from java client program

yogeshgupta
Hi I am trying to connect to hbase in a remote machine from my java program. But I am getting connection refused error. On looking at the error I think it is trying to connect to my localhost instead of the remote machine.

My configuration is like-

Configuration config = HBaseConfiguration.create();
config.set("hbase.zookeeper.quorum.", "10.219.47.22");
config.set("hbase.zookeeper.property.clientPort", "2180");

I am getting the following error-

13/11/15 17:35:08 WARN zookeeper.ClientCnxn: Session 0x0 for server null, unexpected error, closing socket connection and attempting reconnect
java.net.ConnectException: Connection refused: no further information

You misspelled hbase.zookeeper.quorum (dot at the end)

config.set("hbase.zookeeper.quorum.", "10.219.47.22");
