我使用MySQL作为hive的元存储。
在我的JDBC代码中，我替换了
DriverManager.getConnection(connectionUri, username, password);
到
HikariDataSource ds = new HikariDataSource();
ds.setJdbcUrl(connectionUri);
ds.setUsername(username);
ds.setPassword(password);
return ds.getConnection();
我遇到了以下异常：

HikariCP是否支持Hive JDBC？
有没有办法避免调用org.apache.hive.jdbc.HiveConnection.setReadOnly方法？
