Hi,
I'm trying to connect from A java Application to Hbase like this:
Configuration config = HBaseConfiguration.create();
config.set("hbase.zookeeper.quorum", "localhost");
config.set("hbase.zookeeper.property.clientPort", "2181");
config.set("zookeeper.znode.parent", "/hbase-unsecure");
config.set("hbase.client.retries.number", Integer.toString(0));
config.set("zookeeper.session.timeout", Integer.toString(60000));
config.set("zookeeper.recovery.retry", Integer.toString(0));
Connection conn = ConnectionFactory.createConnection(config);
TableName TABLE_NAME = TableName.valueOf("weblog");
Table table = conn.getTable(TABLE_NAME);
Result r = table.get(new Get(Bytes.toBytes("row1")));
System.out.println(r);
I builded the App into a JAR but when running it on the cluster with :
hadoop jar hbaseConnect-0.0.1-SNAPSHOT.jar com.packagename.hbaseConnect.HbaseConnect
i get the following error:
