问题 I am using Pentaho Data Integration Software. I am currently running a Pentaho Job as an ETL. I ETL data from multiple places and put them into a single database table. The schema for all of the places i ETL from are exactly the same. So, other than database connections and a single 'variable' that stores where that data came from, the transformation in Pentaho is exactly the same for each one. So i have a job, that runs each of these transformation. The problem comes in, when i want to make

问题 I'm having some issues when I use the new Kafka consumer connector. I use it as documentation says, I have the connector alone in a transformation and I have a transformation following this one in a job, with a get records from stream step. The problem is that the first transformation, with kafka consumer, never finishes, and it's always running, without receiving nothing. 回答1: Follow me, like below screenshot: 来源： https://stackoverflow.com/questions/47828680/pentaho-kettle-8-kafka-consumer

问题 I installed the Saiku as a plugin in Pentaho 4.8. Saiku comes with the sample data which is SteelWheels. The user is able to choose "Select a cube" in the dropdown box. I just need to know how can I modify the data in that sample data? Where is the file which contains the datastore? And how does the database communicate with the XML file? Thank you 回答1: You have to create a cube in pentaho schema workbench or in pentaho BI Server.. If you are creating it in Schema Workbench then you have to

问题 I am doing comparison between three open source ETL tools Talend, Kettle and CloverETL. I could find with no problem Talend and CloverETL's connector list. But, I cannot find the one for Kettle. Does someone knows them or where can I find them ? Thanks a lot, 回答1: I assume by "connector" you mean input/output nodes and not intermediate transformations. Just looking through the Kettle GUI, I see: Inputs Access CSV De-serialize from file [GH: not sure what kind of file/serialization this means]

问题 We have a Java EE based web application and we want to integrate Pentaho reporting API into this application. So, I'm trying to learn how Pentaho can automatically generate reports containing charts. I have downloaded Pentaho BI server and played with it for a few days. But I'm still clueless about the following issues: How to generate reports dynamically at runtime without loading those *.prpt files. Where I can get a simple tutorial about dynamic report generation What the difference is

问题 I'm using pentaho CDE which is excellent. I've seen you can use a dashboard in standalone with an obscure url like http://localhost:8080/pentaho/content/pentaho-cdf/RenderXCDF?solution=bi-developers&path=/analysis&action=Test.wcdf&template=mantle However I can't get it work neither find a document about it. Does anybody know what the parameters stand for or a link to an official documentation ? For example I'm not sure what is the difference between the solution and the path. Also should I

问题 Earlier I worked with Pentaho reports, where I can create report with pentaho report designer and deploy .prpt file onto into BI server. It will work fine. Now I am looking for a solution where I can put .prpt file in a Java program and run just like jasper reports (.jrxml files). Because I need to integrate Pentaho reports with my web application. I may be asking a very basic question. But I did not find the proper document on this. Please point me to some correct location and a sample code

问题 The "Get files with SFTP" step is able to fetch all the files from the specified source path (over the FTP). But it is not able to read any of the folders exists at the source path. I tried with the Reg-Exp wild cards like .* or * or . etc, but no use. In my use case, the source files always will come in one or multiple folders (like monthly transaction files in month specific folders, or year-wise and month-wise folders in multi-level folder hierarchy etc). If all these folders moved to my
