无法通过Java代码远程连接Hbase

Question

I have installed HBase on Linux Machine(192.168.1.000) and now I have written some sample Code in Eclipse IDE on same linux Machine using JAVA API to communicate with HBase and it's working fine but when I written same java code on windows machine in same version of Ecliple IDE to communicate with HBase on Linux Machine(192.168.1.000). I got:

14/12/02 15:42:40 INFO client.ZooKeeperSaslClient: Client will not SASL-authenticate because the            default JAAS configuration section 'Client' could not be found. If you are not using SASL, you may     ignore this. On the other hand, if you expected SASL to work, please fix your JAAS configuration.
14/12/02 15:42:40 WARN zookeeper.ClientCnxn: Session 0x0 for server null, unexpected error,     closing socket connection and attempting reconnect

14/12/02 15:42:40 INFO util.RetryCounter: The 1 times to retry  after sleeping 2000 ms

whereas my code is:

Configuration config = HBaseConfiguration.create();
config.clear();
config.set("hbase.zookeeper.quorum", "192.168.1.000");
config.set("hbase.zookeeper.property.clientPort","2181");
config.set("hbase.master", "192.168.1.000:60030");
HBaseAdmin hbAdmin = new HBaseAdmin(config);`enter code here`

Please help me to get out from here:

Thanks in advance Abhinav kumar

Answer 1

BindException from your stacktrace is when you try to run your hbase, it will start a co-ordinator service on port 2181 ie zookeeper but as the port might already been in use by some other process, it throws BindException.

Change the port and retry.
