接著上次調試的過程部署時候，發現dolphinscheduler連接tdh時候validationQuery還是select 1

這里懷疑可能是由于dolphinscheduler存在硬編碼問題，修改了代碼也不生效

我們這樣改代碼：

dolphinscheduler-datasource-plugin/dolphinscheduler-datasource-api/src/main/java/org/apache/dolphinscheduler/plugin/datasource/api/datasource/hive/HiveDatasourceProcessor.java

        hiveConnectionParam.setUser(hiveParam.getUserName());
        hiveConnectionParam.setPassword(PasswordUtils.encodePassword(hiveParam.getPassword()));
        hiveConnectionParam.setDriverClassName(getDatasourceDriver());
        hiveConnectionParam.setValidationQuery(getValidationQuery());
//        hiveConnectionParam.setValidationQuery(getValidationQuery());

        if (CommonUtils.getKerberosStartupState()) {
            hiveConnectionParam.setPrincipal(hiveParam.getPrincipal());
            hiveConnectionParam.setLoginUserKeytabPath(hiveParam.getLoginUserKeytabPath());
            hiveConnectionParam.setLoginUserKeytabUsername(hiveParam.getLoginUserKeytabUsername());
        }
        hiveConnectionParam.setValidationQuery("show databases;");
        hiveConnectionParam.setOther(transformOther(hiveParam.getOther()));
        hiveConnectionParam.setProps(hiveParam.getOther());
        return hiveConnectionParam;

hiveConnectionParam.setValidationQuery("show databases;");

修改為這個代碼，不要用getValidationQuery()函數，修改了函數里面的常量不生效，然后打包重新部署即可，經過測試可以連接上tdh的inceptor了
