public static void main(String args[]) throws Exception {
Connection conn;
Properties prop = new Properties();
Class.forName("org.apache.phoenix.jdbc.PhoenixDriver");
conn = DriverManager.getConnection("jdbc:phoenix:hadoop1:2181:/hbase-unsecure");
System.out.println("got connection");
ResultSet rst = conn.createStatement().executeQuery("select count(*) from emp");
