Hi I want to romove non numeric data from a column and pass the numeric data of the form ##.## eg (345.23), but in data validator step on checking "Only Numeric data expected" it is filtering numeric data also and rejecting the values. (i have specified decimal symbol as '.')

Also for date datatype i have specified the datatype as dd-mm-yyyy but id i pass date of format mm-dd-yyyy it is not throwing an error but changing the data and adding one year to it for eg 08-22-1971 is converted to 08-10-1972.
Can anyone help.

Join Rows not working with empty streams

August 17, 2013, 1:33 am

I am running Spoon stable v4.4.0 and running into the following problem: The join rows step outputs no rows if one of the incoming streams is empty. There is a corresponding JIRA issue here: http://jira.pentaho.com/browse/PDI-6273 which claims that the problem is fixed, but unfortunately it doesn't seem to apply to me. Doing the recommended workaround (setting 'main step to read from' to the potentially empty stream) doesn't help matters either.

Here is a screenshot of the transformation:
Kettle.jpg

I have a couple of error handling steps. Univariate statistics produces standard deviations, which in some rare cases (if all values are the same) takes on the value of 0. This, later will cause division by zero errors, so I use the Filter rows and set field value to constant steps for error handling (replacing 0 with 1). Quite logically, either the stream coming from the Filter rows OR the Set to constant step will be empty.

I have tested by splitting the join rows step to 2 join rows steps, and can confirm the problem is caused by the empty stream. Is there a way I can work my way around this problem?

Edit:
I have been attempting to work around this issue by adding dummy fields to both streams (after Filter rows and after set field value). Unfortunately, I can't seem to achieve that either..
- The add constant step does not do anything if the input stream is empty
- The calculator step deos not do anything if the input stream is empty
- The formula step deos not do anything if the input stream is empty
- The generate random value step deos not do anything if the input stream is empty
- Generate rows does not accept incoming streams
- Data grid generates the field even on empty streams but does not pass on other fields in a non-empty stream (it drops the incoming stream)

And that pretty much stops me cold.. I can't even seem to be able to work around the issue.

Can someone direct me to a working & documented example of passing parameters in the url-template.

I created an xAction & resource file.
I defined an input variable {test} with a default value of string type.
I can pass the parameter {test} to the chart title and it works, but can’t seem to pass {test} to the url-template.
Tried many ways with and without <paramName> tags in the resource file, but nothing seems to work.

Thanks in advance.

How to predict with linear regression without saving the model to a file?

August 18, 2013, 7:22 pm

Hi,

I created a job using Spoon design tool to do prediction with linear regression. The job is as follows:
Start --> get_model_transformation --> predict_transformation --> End Job
where
get_model_transformation is to load train dataset and train it using Knowledge Flow.
Table input --> Knowledge Flow
and the Knowledge Flow is to train the model with linear regression.
Kettle Inject --> Training SetMaker --> LinearRegression --> Serialized Model Saver
predict_transformation is to read the test dataset, calculate the predicted value and then save it to the database.
Table input --> Weka Scoring --> Update

Because in the job, the model is saved first to a file and then the file is read for Weka Scoring, there's an overhead for file I/O.
I want to reduce the file I/O overhead so the job will run faster.
Q: Is there any way to predict with linear regression without saving the model to a file (may be save it in memory)? Any other advice to make the job faster is also welcomed.

Many thanks,

Kusuma

Kettle spoon throwing error ORA-00904: "X_ROLE": invalid identifier

Hi,
I am trying to run a simple select command from spoon transformation step and is throwing error.
Where as the same statement from sqldeveloper is working fine.
select x_role from SIEBEL.S_PARTY_PER

The connection created in Spoon is JDBC with same user/password as sqldeveloper db connection.
If I remove that column and do a
select * from SIEBEL.S_PARTY_PER and do a preview then I am seeing results for all columns except x_role.
But that column does exist in database table as I could query using sqldeveloper client.

I tried "x_role", "X_ROLE", x_role as ROLE etc... as well in the select statement. But giving same error.

Hi, I tried to get the customise Results to get the cell values. Here is the code and got stuck while casting.

Connection connection;
Class.forName("mondrian.olap4j.MondrianOlap4jDriver");
connection = DriverManager.getConnection(connectStr, null);
=>OlapWrapper wrapper = (OlapWrapper) connection; //getting error here
OlapConnection olapConnection = ((OlapWrapper) connection).unwrap(OlapConnection.class);

java.lang.ClassCastException: mondrian.rolap.RolapConnection cannot be cast to org.olap4j.OlapWrapper

I just followed the link "http://www.olap4j.org/olap4j_fs.html" for ref. Previously i tried to execute the query (as given in the documentation), that uses Result res = connection.executed(query); (which is deprecated and working fine for now). Now trying to create statement and execute to get cellset.

Using measures in different axis / row calculations

Hi folks!

I have a question regarding MDX queries on Mondrian:


I have a SUBSCRIPTION cube about magazine subscriptions with two measures : NEW SUBSCRIPTIONS and RETURNING SUBSCRIPTIONS.


I'm trying to make a query that displays both measures for two periods of time, and also the percentage growth in the period.
I'm using PARALLELPERIOD to get the % Growth between time members.


Example :

DESIRED VIEW - EXAMPLE


But I can't get this view using standard MDX, because I can't put measures in both axis.


The result I've got so far (not user friendly):

Using measure ON COLUMNS:

RESULT - NOT USER FRIENDLY


Using measure ON ROWS:

RESULT 2 - NOT USER FRIENDLY




How can I do that first desired view in Mondrian?


Thanks in advance.

I downloaded Pentaho Design Studio 4.0 for Mac and installed on MacBook Pro (OS X Version 10.8.2). I started PDS through Eclipse and loaded HelloWorld.xaction. When I tested it, I found following issues:
1. Pentaho Server URL field didn't show up correctly. I didn't see any space to fill URL correctly
2. I copied "localhost:8080/pentaho" to the URL, but nothing happpend when I clicked test button
3. I clicked Generate URL, seems it created the Generated URL correctly, but I can't run it. When I click Run, nothing happen
4. When I copied the generated URL to a web browser, it worked as expected
5. Browser URL is not working either

A screen shot image is attached for your reference.

Please let me know if anyone had similar experience with Mac OS X before.

Thanks.
