通过JDBC访问Thrift Server，进而访问Spark SQL，进而访问Hive
String sql = "select name from test where age = ?";
String sql = "select name from test where age = ?";
Connection conn = null;
ResultSet resultSet = null;
try {
Class.forName("org.apache.hive.jdbc.HiveDriver");
conn = DriverManager.getConnection("jdbc:hive2://DaShuJu-040:10000/hive?"
+ "hive.server2.transport.mode=http;hive.server2.thrift.http.path=cliservice",
"root", "");
PreparedStatement preparedStatement = conn.prepareStatement(sql);
preparedStatement.setInt(1,30);
resultSet = preparedStatement.executeQuery();
while(resultSet.next()){
System.out.println(resultSet.getString(1));//此处的数据应该保存在Parquet中等
}
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
} finally {
try {
resultSet.close();
conn.close();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
