----------------------------------
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
Components: documentation
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) {
