Race Condition on rows

March 26, 2014, 8:48 am

Hi,
maybe it's absolutely easy, but I could not find a solution so far.

My transformation is reading up to 5000 rows from a table in a staging area.
Then it does some transformation steps and finally it's populating the data to some tables in the warehouse schema.

It is absolutely crucial that the rows never change their order.
The select statement is following a chronological index.
I used order by and force index.

So after the Table Input step the row set is in the right order (I hope so...).
At least it is if I execute the select manually...

But I can see, that in the Insert/Update step the race has not been decided :(

Is it really necessary to sort the sorted result again in a temp file in a Sort step?

I tried to get rid of duplicate rows, but that doesn't work either. It just drops the 'wrong' rows. Means, it keeps the oldest and skips the newest.

So what is the right way to run a transaction, so that the output happens in exactly the same sequence as the input?
Or, as an alternative, that I can sort out the oldest rows?

Thanks for any help

Hi everyone, Im new with Kettle and i need your expertise to solve the next transformation:

I need something like this.

id Date Expected Result

07/02/2014
07/02/2014

10/02/2014
07/02/2014

2
07/04/2014
05/04/2014
2
08/04/2014
05/04/2014

I need that if the difference between the date of the row and the row before is less than 7 days, keep the minimum value, if the difference of dates is >7 keep the date of that row. If the "id" change always keep that date and take it as the new minimum date. I hope my English is not so bad and i have explained myself, thanks in advance!!

Is there a Step (Spoon) I could use to connect to a server and download the output generated to my PC? Here is exactly what I am trying to do:

When I copy paste this link in web browser(x - ip host and port number):

http://XXX.xx.xx.x:xxxx/ws/spaces/1hpv/connections?q="interaction id":1e35bda0e2&c=sentiment&c=sentiment.weakpositivesentiment

I get the following output (Json format)

{"mn":1,"mx":1,"p":1,"ps":10,"np":1,"nr":2,"qt":"0.028","r":[{"a":{"c":"sentiment","v":"interesting debate going on re","id":3848290697236},"m":1},{"a":{"c":"sentiment.weakpositivesentiment","v":"interesting","id":7146825580549},"m":1}]}

I am trying to write a transformation to do this and download the file to my PC and not sure which steps to use.

Thanks.

Dashboards.context.roles is undefined

When testing on my localhost, a javascript file retrieving the user roles using "Dashboards.context.roles" returns the role array set up in the administration console for the logged in user.

However, after deploying the bi-server to another server and setting up the roles within the administration console, Dashboards.context.roles is undefined.

The only difference between the two is that on the new server, the BI Server is accessed via an IP address, not "localhost:8080"

I followed the instructions here to ensure that security was enabled between the BI Server the Admin Console and then restarted the server. The admin console connects to the BI server fine, but still the roles for the logged in user are undefined (as well, the user is undefined).

Does anyone have any ideas?
Thanks in advance!

Univariate Statistics from a Database Repository

Hi there

I was wonder if someone could provide some help with an issue I have with Univariate Statistics.

When the attached transformation is run as a stand alone transformation or from with a File Repository it runs as expected.

When I import this transformation into a Database Repository and run, I get an error:

Code:
2014/03/27 14:45:18 - Univariate Statistics.0 - ERROR (version 5.0.1-stable, build 1 from 2013-11-15_16-08-58 by buildguy) : Unexpected error

2014/03/27 14:45:18 - Univariate Statistics.0 -    at java.lang.Thread.run(Unknown Source)
If I save the transformation after this failure, the Input Fields are blank when I reopen the transformation, so not sure if that is a clue.

This is run from PDI Spoon 5.0.1.A Stable on a Windows XP PC. The Database used for the Repository is MySQL.

Included in the zip is a transformation and a simple CSV with test data. Output is an Excel spreadsheet. The Parameter {processDir} will need to be set for the environment this is run is (processDir is used instead of a built-in variable for the use within a Database Repository)

I'm not sure what I am missing in order to get this to run correctly, so appreciate any help/comments.

I have a date column (Text file input) whose format is different for each run. Any way auto detection of date format is possible?
Have seen Matt Casters mention it in a jira case in comments section. Have included the link as well
Quote:
http://jira.pentaho.com/browse/PDI-10477
Or is there a requirement to automatically detect which date format a date is in and then pick the right one out of 2 or more formats?
This is exactly what i am trying to accomplish.
Thanks in Advance. I am using PDI-5.0.1

unable to publish pentaho-platform-api.jar to remote repository while building

Hi,


I am new to Pentaho. I installed Pentaho software and could view sample reports from User Console.
Now I want to build Pentaho software from the open sources available through Community Edition.


As such I downloaded the sources and imported in Eclipse creating projects viz,
pentaho-platform-api, pentaho-platform-assembly, pentaho-platform-core, pentaho-platform-extensions,
pentaho-platform-repository, pentaho-platform-scheduler, pentaho-user-console.


I could build successfully the pentaho-platform-api project with the default target in ant
generating 'pentaho-platform-api-TRUNK-SNAPSHOT.jar'.


But when trying to build with 'continuos' target in ant which builds the jar and publishes the generated jar to remote repository, it
is giving the following error.


---------------------
maven-publish-dependencies:

------------------------


Can anyone help me out from this.


Also I chose randomly pentaho-platform-api project to build first. I want to know the order of the projects to be followed for building.


Also, I would like to know and it would be very helpful to me if there is a tutorial explaining how to build pentaho software from open sources so that I can know what steps are needed and what configuration should be done to build pentaho software.
Could you please suggest?




Thanks and regards,
Raman Kumar.

Hello.
There is simple data.
Time Country value_per value
1998 USA 1.37 1000
1999 Canada 2.37 3000


By default i get the ratio of agregated values ((value1 + value2)/(value_per1+value_per2))

However, I need to calculate a measure according to the following formula (value1/value_per1 + value2/value_per2). In other words, i need to get the individual values for each point (value1/value_per1 ratio) and then get the sum of these values.

What formula should I use?

Hello everybody,

I spent my all day looking for a solution, but I am out of ideas.

biserver-ce: 4.8.0
schema workbench: 3.6.1

I have no issue publishing a report with prd. Unfortunatly it doesn't work for psw. The only error I can read is "Unable to publish your file. Please try again or contact your system administrator for assistance". Nothing more, neither in logs from biserver, neither psw.

Aditionnaly I am not able to create or to manage data sources from the biserver.

All connections to DB have been set and successfully tested.

I would be very happy if somebody could help me, and at least explain me how I could manually transfer and activate the schema.

Thank you very much
