----------------------------------

             Summary: doc update for how to create non-shared HConnection
                 Key: HBASE-11518
                 URL: https://issues.apache.org/jira/browse/HBASE-11518
             Project: HBase
          Issue Type: Bug

    Affects Versions: 0.98.4, 0.94.21
            Reporter: Qiang Tian

creation for non-shared connections has changed since hbase-3777, but the doc still remains
the same...

a simple test program:
public class testHbase2{
        public static void main(String[] args) throws Exception {
                Configuration conf = HBaseConfiguration.create();

                conf.set("hbase.zookeeper.quorum","localhost");
                conf.set("hbase.zookeeper.property.clientPort", "2181");
                conf.set("hbase.client.instance.id", "2");
                HBaseAdmin admin = new HBaseAdmin(conf);

                conf.set("hbase.client.instance.id", "3");
                HBaseAdmin admin2 = new HBaseAdmin(conf);
        }
}

  public static HConnection getConnection(final Configuration conf)
  throws IOException {
    HConnectionKey connectionKey = new HConnectionKey(conf);
    LOG.info("###create new connectionkey: " + connectionKey);
    synchronized (CONNECTION_INSTANCES) {
