【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 一、 首先去官网，因为是纯英文的。所以将其进行了翻译。 https://community.hitachivantara.com/s/article/data-integration-kettle 点击以下画红色框的线，对其进行下载。 下载完毕后，将其进行解压 Kettle是纯JAVA编程的开源软件，本地环境配置JDK1.7以上即可运行，解压后直接使用无需安装。 二、在环境变量中配置pentaho_java_home变量。值就是本地的jdk路径 配置完毕后，点击Spoon.bat 打开后耐心等待一会儿。 三、创建数据库的连接 点击转换，切换主对象树。可以看到DB连接。点击DB连接。 选择mysql的连接。输入相关的连接信息。 然后点击测试，出现以下的错误。 这是由于没有mysql的驱动包所导致的。所以要在pdi-ce-8.3.0.0-371\data-integration\lib下放入mysql的驱动包。找到对应的mysql版本的驱动包,如下载版本过低的驱动包会出现。 Unknown system variable 'query_cache_size' 这个错误，从而连接不到数据库。 我这下载的是mysql-connector-java-5.1.8.jar这个驱动包。可以看到测试连接成功。 点击确认 四

Pentaho JNDI source name as parameter (Multi-Tennant)

由 て烟熏妆下的殇ゞ 提交于 2019-12-20 07:36:53
问题 I have googled this for the last half an hour, and found hits for pentaho parameters etc but nothing that appears to ask or answer this question. I have a set of reports that are the same for each customer, but need to connect to different databases depending upon the customer who is running the report. So my idea is to pass the JNDI data source name to the report at runtime as a parameter, so that the customer will connect to the correct database. Is this possible, or is there a better way

pentaho spoon/pid: how to move files to folders with different name everytime?

由 穿精又带淫゛_ 提交于 2019-12-20 05:28:23
问题 I have new text files every month from where I extract the data and do some transformations. In the end of every month, I need to move these files to a folder with current date in name. Which means, the destination folder's name is different everytime. I made a step before move files that creates a folder and its name is current date (exp: 2019-06-01, 2019-07-01), but then on move files step, I don't know how to specify the destination folder. Guess "wildcard" is only used for source...

How to retrieve OUT parameter from MYSQL stored procedure to stream in Pentaho Data Integration (Kettle)?

由 一个人想着一个人 提交于 2019-12-14 00:24:14
问题 I am unable to get the OUT parameter of a MySQL procedure call in the output stream with the procedure call step of Pentaho Kettle. I'm having big trouble retrieving OUT parameter from MYSQL stored procedure to stream. I think it's maybe a kind of bug becouse it only occurs with Integer out parameter, it works with String out parameter. The exception I get is: Invalid value for getLong() - ' I think the parameters are correctly set as you can see in the ktr. You can replicate the bug in this
