file delete issues in Windows multi core environment

≪ Previous: Hadoop Online Training

HI, we are runing PDI 4.2 in a Windows virtual environment (ESX). Everything appears to work fine when the server is configured with a single core, but when we scale up the server to mulitple cores we are running into problems. We have been encountering issues when attempting to delete a file where the system is throwing the following exception:

ERROR 11-10 14:26:26,353 - Is Full Load - org.apache.commons.vfs.FileSystemException: Could notdelete "file:////.../..../...foo.txt".

Looking for anyone who has experienced similar issues. The problem exists in multiple PDI jobs. We have looked a the apache doDelete code, and it is not doing anything fancy, so we don't believe this is the root cause. Wondering if there is a compatibility issue with the ESX virtual environment.

Apologies in advance if this is a dumb question, but can someone explain how to understand this log?

Call DB Procedure 3 2 - Finished processing (I=0, O=0, R=5, W=5, U=0, E=0) - What does each letter mean? I am assuming I = input?, O= output? R = read? W = written? No Idea what U or E means. I'm assuming these numbers pertain to rows or records?

Thanks

Hi,
I have strange situation.. when i create an folder 'folder1' with joe user (that has admin permissions and consumer) and I create a new folder 'folder2', only the admin permission is inherited. I read many posts that folder permissions are inherited, but this is not happening, it would be a bug?

This is pretty weird. I have a form on one page that's working when I have the method set to GET. This is the URL.

http://50.57.92.90:8080/pentaho/cont...sword=password

If I change the method to get it works. But if I use POST it won't work at all. Is this a bug or is passing parameters to reports only capable via get? Seems a bit odd to me.

Here is the html I'm calling from. Dead simple.

Custom plugin MetaData Injection and step-attributes.xml problem

November 13, 2013, 2:12 pm

≫ Next: Sort Row step output wrong result

≪ Previous: Can't access report on BI Server With Post, but can with GET

I wrote a custom step plugin, and would like to wire it for MetaData injection.
I read the wiki
(http://wiki.pentaho.com/display/EAI/...+Injection+API)
and my understanding is that I just need to implement the
getStepInjectionMetadataEntries() and injectStepMetadataEntries() methods in my StepMeta?

Say my new plugin step is called Fred. So I have
FredStep.java, FredStepMeta.java, FredStepData.java, FredStepDialog.java

I added StepMetaInjectionInterface to my FredStepMeta declaration:
FredStepMeta extends BaseStepMeta implements StepMetaInterface, StepMetaInjectionInterface

BaseStepMeta .getStepInjectionMetadataEntries uses attributes, and should have loaded "step-attributes.xml", but that does not seem to
work for my custom step plugin.
I placed the step-attributes.xml file into the plugin directory, and it is getting deployed along with the plugin.xml file, but it is not getting loaded by the
BaseStepMeta.loadStepAttributes().

What do I need to do to add "step-attributes.xml" so it will get read?

thanks

Hello, here is the details:

I use PDI 4.4.0 community binary on Linux

I have a data file in text format, which contain about 50,000,000 rows.

I load the data and send it to a Sort Row step, I keep sort cache remain on 1,000,000

Then I find the result is wrong.

I change the sort cache to 100,000,000, then I got the right result.

I see on Jira some people report a issue relative sort cache, is this similar? http://jira.pentaho.com/browse/PDI-10580

Hello Everyone,
I want to save a log file(.xls), with a column/field "Step-name".
The column must display the name of the steps, in which error has occurred.

Like consider the file I've uploaded.
1. For "data-validator" step, in its settings, I've used "${Internal.Step.Name}" variable as a value in "error description".
Such that if there would be an error, then in the log file, the "error-description" field would show the step name, i.e., "Data validator".

2. Similarly, this happens for the unique rows.

3. But for the "database lookup" & "Table-output" steps, its not possible.
Tell me the solution for this, please.

I'm uploading snapshots of the files, to make you understand what I want.
Thank You.

Hi,

Has somebody here tried to parse the Apache Tomcat access log with PDI? I am looking for a way to interpret the data like IP, timestamp and accessed ressource and to write it to a database.

Here an excerpt how the lines look like:

Code:

10.61.4.5 - - [12/Nov/2013:00:20:38 +0100] "GET /birt/run?__report=vailable.rptdesign " 200 4320

What would be the best approach here? Using the RegEx step?

REST API to generate report and send Email

≫ Next: Pentaho does display chart in an web application

≪ Previous: Parste Apache Tomcat access log with PDI?

What i am trying to do is to generate a report and send it as an attachment via email. I have configured email_config.xml and have tested it by running the example 'Burst Sales Report'. From the documentation of reportViewer there seems to be a reportViewer parameter called 'destination' and the document states that 'If email settings are configured in the BI Platform, this parameter will allow you to specify a single email address to send the rendered report to.'

However this did not work for me - an example URL i used was
http://localhost:9080/pentaho/content/reporting/reportviewer/report.html?solution=steel-wheels&path=%2Freports&name=Country.prpt&locale=en_US&destination=xyz@gmail.com

However no email was received .

Couple of questions:
1) Can the REST API be used to generate a report and send it as an attachment in an email
2) If there is no such API what the best way to generate and email a report

I am using Pentaho Bi Server CE version 4.8

thx

In the Looping Job which contains two transformations:

1. Obtaining values from flat file and assigning these to the variable
2. Using the variable to insert data into the Production Table.

The first Transformation throws up an error when the flat file contains more than one value in it.

Finally, I intend to run my job depending on the number of values contained in the flat file.

Do let me know at the earliest if there is a workaround.

[PRD] Image on background is ok when run as PDF but not when run as Excel

November 14, 2013, 5:15 am

≫ Next: Using lookup databa

≪ Previous: Gradient Color in Bar Chart

Hello,

I am facing some troubles learning how PRD works: I want to put some text over one image. On PRD I can see that the label(text) I am using is highlighted alerting me that it is over the image. But that's exactly what I want. If I run the prpt as PDF everythings goes well, the image is on the background (not as a watermark, just as a backgroud image), nevertheless if I choose to run as Excel then I only can see the image.

I've made a little test to ilustrate this:
howThisWorks.prpt

The output on pdf is like:pdf.jpg

but in excel is: excel.png

Is this the expected behaviour on excel or I am doing something wrong?

If this is how PRD/Excel works, is there any way to tell the report to prioritize Text over Images when exporting? I don't mind that the images are not showed as long as the text is... but now the text isn't showing.

Any tips will be highly appreciated.
Regards.

I really don't understand that because all of the source MySQL columns that become a smallint in SQL Server are defined as tinyint(1) in MySQL, and they all have data in them of 1 or 0, no "N" values appear anywhere.

What's going on and how do I work around it?
