解决方案：重新安装jdk8，并配置环境变量。

As mentioned in Pentaho Components Reference, Only Java 8 is supported by Pentaho Data Integration, So it is not recommended to try out Java 9 or Java 11 at the moment (until they release a version which supports above Java 8).

jdk8下载：

https://www.oracle.com/java/technologies/javase/javase-jdk8-downloads.html

下载地址：https://download.oracle.com/otn/java/jdk/8u251-b08/3d5a2bb8f8d4428bbe94aed7ec7ae784/jdk-8u251-windows-x64.exe?AuthParam=1592214346_b478a010230ec68704d8566f35aa3c18

jdk环境变量设置：https://jingyan.baidu.com/article/6dad5075d1dc40a123e36ea3.html

安装成功后，会有Rusn configurations出现。

创建mysql连接:

create USER 'mytest'@'%' IDENTIFIED BY 'admin';
GRANT ALL ON *.* TO 'mytest'@'%';

FLUSH privileges

mysql-connector-java-5.1.5-bin.jar 放到lib下测试。

连接Mysql报错：

JDBC Drivers Reference - Pentaho Documentation

MySQL

Oracle

https://dev.mysql.com/downloads/connector/j/5.1.html

REF:https://help.pentaho.com/Documentation/8.0/Setup/JDBC_Drivers_Reference

最终把mysql-connector-java-5.1.49-bin.jar放到lib文件夹下，成功了。
Kettle-pdi-ce-7.1.0.0-12data-integrationlib

MS SQL SERVER

JDBC Driver

It is recommended to use the official Microsoft JDBC Driver for SQL Server (v4.0) to connect PDI to a Microsoft SQL Server.

For Integrated Security authentication, the JDBC driver requires the bundled "DLL" file to also be added. The DLL file can be added to the "libswt/win64/" directory of the data-integration client.

主机名       : localhost
端口           : 1433
数据库名:MyDatabase

【解决方案】安装jdbc包：sqljdbc42.jar 放到kettle的lib下。TCP/IP设为Enabled和SQL SERVER BROWSER启动。

ref -jdbc下载;http://www.java2s.com/Code/Jar/s/Downloadsqljdbc420jar.htm

ref - 打开Browser，：https://blog.csdn.net/jacky4955/article/details/45365049

REF: 启动TCP/IP : https://blog.csdn.net/qq_31010431/article/details/71263873

必须要重启生效。
