Regex Evaluation (group capturing) documentation error?

February 15, 2016, 6:05 am

Hi all,

I'm quite new to PDI and I ran into something unexpected using the Regex Evaluation step in PDI (5.4.0.1-130, Windows 10)
The goal was to capture a piece of a large string, hence the Regex Eval/ Capture Group step.
The documentation page shows this example to isolate two groups from one input string:
^"([^"]*)" - (\d*) posts$
I could not get this to work until I changed the first character to a backslash instead of the caret.
\"([^"]*)" - (\d*) posts$

Is this an error in the documentation, or am I missing something else? First thought was a version difference, but the behavior is the same on a RegEx learing/testing page. Slash works, caret does not. And this is probably more of a question to ask in the documentation wiki comments; doesn't look like I can use the forum login for that. Or does it take a while for those to get synchronized?

Thanks.

Report designer, subreport does not appear in pdf report

Hi,

Pentaho version: 5.4/6.0.1 EE
OS: Redhat Enterprise Edition 7/Ubuntu 14.04/CentOS 6

I have created a report that it is referenced by a Pentaho Report Output step in a kettle transformation. The report has been generated without any problems at my design environment (Ubuntu/Pentaho 5.4 EE) but it fails to load a sub-report section at the two production environments (RH 7/Pentaho 6.0.1 EE, CentOS 6/Pentaho 5.4 EE). I would provide more information but i am not able to find any form of logs regarding the generation of the report, apart from the kettle logs that doesn't give any information regarding that.

Sending Email Alerts (success/ failure) -- do you need real email sender?

Hi there --

I'm pretty green/ new when it comes to things related to mail servers, etc.

I was told by our tech team that an actual email address is not required to send emails (only to receive them perhaps) --- perhaps some sort of alias can simply send alerts.


Anyway within the context of Pentaho Data Integrations "Send Mail" job entry --- in which I've typically been entering SMTP Server info + user authentication + password ---- well I guess what I'm asking is, what's the best practice here in terms of sending alerts for success/ failure for ETL jobs?

Like, I wouldn't feed in my personal email address to send alerts, right? It would be prudent to set up a dummy or 'no-reply' email address, correct? But do I just set up a traditional corporate/ whatever email address for this purpose?

Any thoughts welcome -

Sub-transformation/Mapping Question

Hello All,

I have a requirement to use files across multiple transformations. These transformations are to be used in various jobs.
For this reason, I intend to write the transformation which will do operations on the file (Say Load-Transformation). This Load-Transformation shall be used in another transformation where the fields are to be used.
How can this be achieved? I have tried to use sub-transformation (mapping) but could not understand how to use for this scenario.

Purvesh Kulkarni.

Help reading variable lenth record files into tree database tables

Hello everyone,

Being new on Kettle and i'm studying it and looking for hints.

I have to put the attacched files into three database tables.

The information are organized into different blocks starting with a line start label ST001 and ending with ED001.

You may thus consider ST001 and ED001 like headers and footers of a unique block of information.

The other records within this block start with a block line sequential number (7 bytes) + a 3 bytes record type.

For each block I have to populate 3 databases related tables:

table_1 ---->> contains header
table_2 ---->> contains record type 001
table_3 ---->> contains record type from 002 to 006

table_1 is related with table_2 (table_2.id_table_1 = table_1.id)
table_2 is related with table_3 (table_3.id_table_2 = table_2.id)

Can you provide information about the steps of the transformation process?

Thanks a lot,


Best regards

Would someone know how to explain this property?
Thanks in advance to those who will help me.

Hi

I have a report sql with columns of different data types.

Please let me while designing the report in Details section what field type should I add for clob data type.

Also for the columns as Big Decimal, Integer and Number type I am using the same number-field in Details section. Will it be fine?. I am not sure for Integer and Big Decimal since both classes are different.

Please let me know in case you have faced any issues with these fields.

Thanks,

Data validator halts execution when reaching invalid field.

February 16, 2016, 5:39 pm

Hello everyone. I'm a new Pentaho user and have gotten stuck on an error handling issue for a simple ETL routine. Here are the details of my setup:

  • I am writing a transformation to read a csv-formatted table, check that all the row entries are formatted properly, and write out to a database.
  • I am using the Data Validator for the middle step, to verify that the data type of the first field ("rim_no") in the csv table is a number.
  • I have enabled error handling from the Data Validator, with provision to write out bad rows to a text file.


Here is the problem:
  • The first time it comes to a row with an invalidly formatted first field (for example, a string rather than an integer), the transformation halts execution with the following error:


2016/02/17 00:59:06 - Data Validator.0 - Read row #505 : [40229], [2013-04-26 00:00:00], [10], [Active ], [95], [2013-04-26 00:00:00], ...2016/02/17 00:59:06 - Data Validator.0 - Wrote row #0 : [40229], [2013-04-26 00:00:00], [10], [Active ], [95], [2013-04-26 00:00:00], ...
2016/02/17 00:59:06 - Data Validator.0 - ERROR (version 6.0.1.0-386, build 1 from 2015-12-03 11.37.25 by buildguy) : Unexpected error

2016/02/17 00:59:06 - Data Validator.0 - Unexpected conversion error while converting value [rim_no String] to an Integer
2016/02/17 00:59:06 - Data Validator.0 -
2016/02/17 00:59:06 - Data Validator.0 - rim_no String : couldn't convert String to Integer

2016/02/17 00:59:06 - Data Validator.0 -
2016/02/17 00:59:06 - Data Validator.0 -

I have read everything I can in the forums, and on Google, about this and related issues.
Here is my question:
  • Why does Data Validator abort the transformation when it comes across a badly formatted entry? I thought this was precisely what it was designed to handle. And why is it trying to convert the bad format (String) to an Integer, instead of triggering the error handler?

Hi forums,


I'm new in CDE and I need your help.


My problem is that I'm trying to do a responsive dashboard, for that I followed this tutorial : http://pedroalves-bi.blogspot.fr/201...orial-and.html


The dashboard was already created in blueprint and I want to switch it in bootstrap, and almost everything is responsive, except the most important things in the Dashboard the Data-tables. The Data-tables keep the same size and I don't know why. I've tried a lot of things, but nothing seems to work.


Can someone help me please ?
