The cause of this error is that the computer used is 64-bit, but the MySQL 64-bit ODBC driver and the qt odbc driver do not know where it is incompatible, so the connection may fail. Reinstall MySQL's 32-bit ODBC driver for configuration, and connect again (64-bit and 32-bit drivers can work normally, this is not scientific = ). = ===============================

Hive has been used for a while, but no related logs have been written, because hive is mainly used in the create table, upload data, and crud processes. Later, I needed some frequently used methods in my work. I learned that hive supports UDF (user define function). I have read some articles and found that UDF writing is also very simple, inherit the UDF and over
