chenerlu commented on CARBONDATA-956:
-------------------------------------

As I konw, this is similar as using JDBC to quey hive table. It contains several steps:
step1: loading driver
step2: specify your JDBC url and get connection through driver, like connection = DriverManager.getConnection(url,
"cel", ""); 
step3: specify your query sql, like String querySql = "SELECT * FROM CARBON_TABLE";
step4: create statement through your connection;
step5: use executeQuery api, you can get the query result.

You can have a try, if you still have some question, feel free to let me know :)
