一、连接
public static void main(String[] args) throws SQLException {
try {
Class.forName("org.apache.hive.jdbc.HiveDriver");
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
System.exit(1);
}
String uri = "jdbc:hive2://master:10000/default";
Connection con = DriverManager.getConnection(uri, "", "");
String sql = "show tables";
System.out.println("Running " + sql +": ");
Statement stmt = con.createStatement();
ResultSet res = stmt.executeQuery(sql);
System.out.println(res);
while(res.next()) {
System.out.println(res.getString(1));
}
}
