Where do you put the hbase-site.xml? In the resource folder of theproject or on the cluster?

I usually put those connection params inside the hbase-site.xml thatwill be included in the generated jar..

    I want to add that it is strange that the client wants to
    establish a connection to localhost but I have defined another
    machine.

        Hi,
        I implemented a job which reads data from HBASE with following
        code (I replaced the real address by m1.example.com
        <http://m1.example.com>)

                protected Scan getScanner() {
                    Scan scan = new Scan();
                    Configuration conf = HBaseConfiguration.create();
                    conf.set("hbase.zookeeper.quorum", "m1.example.com
        <http://m1.example.com>");
        conf.set("hbase.zookeeper.property.clientPort", "2181");

                    try {
                        table = new HTable(conf, "table");
                        table.getScanner(scan);
                    } catch (IOException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }
                    return scan;
                }


        My code works well when I execute it local but when I execute
        deploy it on the cluster then I get following exceptions:
