问题 I installed a fresh copy of Windows 10 (Education version)and discovered that when I run Pentaho PDI (version 5.4) that I am unable to connect two steps together. Normally there is a dialog window that opens where you can select the add hop but nothing. I installed the JRE and JDK versions of Java. No other issues that I have nothing with other application using Java. I did make the discovery this evening if I place two steps on the work surface and then attempt to execute the transformation,

问题 I'm setting up pentaho for the first time. It is able to see mysql but when I try and set up the initial repository it give me this error: org.pentaho.di.core.exception.KettleAuthException: Incorrect password or login Seems to want an admin (username) password.

For instance ${DB_HostName} , and ${DB_Name} etc. Then just put it in your kettle.properties: DB_HostName=localhost You can see what fields that support variables by the S in the blue diamond. 来源：

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...

问题 I have a requirement where I need to fetch records from multiple tables. The primary table is having one-to-many relationship to other tables. My data source is Oracle DB.

问题 It's quite simple to use row denormaliser to achieve pivots when we have few records which can be written manually in denorm step,but what when there's hundreds of thousands of records? I tried using etl metadata injection step, but I was unable to achieve my desired output. Here is the link to my previous post where my source data has been defined. and here is what I have tried row denormaliser options pivot_inject_etl_metadata.ktr 回答1: Try something like this: pivot_inject_etl_metadata.ktr

问题 As the title says, I'd like to know how to create a folder with current date(dd/mm/yyyy) (on Job).

Thanks :) 回答1: That answer is also from 2014, better and newer versions of PDI are out, and this answer is overcomplicating the task. Though you do need to create the folder name in a KTR, you can just use the 'Create folder' Job step. I'm pretty sure you cannot
