Ideas for logging errors / rejections from Lookup step

May 20, 2015, 12:02 am
$

I have been searching the forum but I cant seems to get the question right so all the answers are irrelevant.

What I would ideally like to do is catch the error output from a DB Lookup step (ie where the lookup failed).
Then log this fact, along with values from the row in error, to a generic error table.
Last time I did this was in Pl/Sql and the table was a value pair basically column/field name and field value.
So the one construct was used for all processes.

With kettle I can see that you can right click and select 'Define Error Handling'
that requires a target step. Unfortunately all the doco simply send this to the dummy step so I cant really guess what type of step it should refer to.
AND the step has to be one of the outputs from the lookup step.

To experiment I sent the reject stream to a 'Text File Output' step and the reject row does get logged (to a file).
However nothing set in 'Define Error Handling' appears there and in fact that whole bit can be turned off and the results are the same

I don't want to write a whole pile of files from every lookup and then have to write another job to go and gather them up - all with different formats by now; then to put them, by magic, into the database so users or administrators can see the errors along with other outputs.

Does anybody have any suggestions as to a more appropriate step type to send errors to?
Also how to turn a row of a stream into value pairs (opposite of Row Denormaliser (and the opposite is not Row Normaliser))

Thanks

Hi All,

I appreciate and thank you if anyone of you assist me in enlarging the report if we click on the particular panel of the dashboard. As of now, we could view the report within the panel which is very very small with horizontal and vertical scroll bars, which is not actually good looking. Expecting your valuable answers..

C-Tools Update Has Broken My PRPT Reports

Hi All,

I hope someone here can help.

I am currently running the 4.8.0 version of the web application.

On Monday I updated C-tools using the "ctools-installer.sh" script (which is now v.1.48). After the update I double checked my CDE dashboards and CDA files to check they were all fine which they were.

Anyway yesterday I got a report that the PRPT reports weren't working. Looking in Chrome's Developer Tools it seems to be a problem with "/system/pentaho-cdf/js/lib/CCC/jquery.tipsy.js" - "Uncaught TypeError: Cannot read property 'fn' of undefined" related to this line "$.fn.tipsy = function(options, arg) {".

Any ideas?

Involuntary trimming with Text file input?

Hi, I'm a student using Kettle to try to preprocess some txt files and separate them.

The process works fine, and it separates the categories just fine, however, Kettle seems to be trimming the longer lines on its own initiative.

For example, a line that in the "Get fields" GUI shows up as 270 chars long is shown fine. I've set the field to have 350 and there's also no trimming. However, the actual file, and the "Preview Rows" GUI is trimming them.

Anyone have an idea?

Thanks!

How to store in PUC Analysis Month number value instead Month name value

May 20, 2015, 5:09 am

Is possible somehow store column number instead column name in filter of saved analysis? My version of Pentaho User Console is 5.3. This is my level element in mondrian for month:
Stored values in database:
Values in month_name are: [Jan, Feb, Mar, Apr,...] Values in month_number are: [1,2,3,..]
HTML Code:
<Level name="month" visible="true" column="month_number" ordinalColumn="month_number" nameColumn="month_name" type="String" uniqueMembers="false" levelType="TimeMonths" hideMemberIf="Never" caption="%{polymis.dimension.timedimension.hierarchy.level.month.caption}">
        <Annotations>
          <Annotation name="AnalyzerDateFormat">
            <![CDATA[[yyyy].['Q'q].[MMM]]]>
          </Annotation>
        </Annotations>
      </Level>
Above you can see that i use column="month_number" so i thought that the value that will be stored in analysis file below like filtered value, but instead there is the value from "month_name", for me this is invalid because i use localized values of months, so when i turned my language into another one this will not work for me in Pentaho user console. The stored value should be rather
HTML Code:
<filters>
        <filter formula="[timedimension].[month_name]" viewFilterEnum="MULTIPLE">
            <predicates>
                <predicate ordinal="1" operatorEnum="EQUAL">
                    <member formula="[timedimension].[2010].[Q1].[Mar]" caption="Mar" pos="0"/>
                </predicate>
            </predicates>
        </filter>
    </filters>
The result should be like below or something like that
HTML Code:
<member formula="[timedimension].[2010].[Q1].[3]" caption="Mar"
    pos="0"/>

Buenos días,

tengo una tabla con datos en SQL Server que se rellenan con datos que vienen de Pentaho, si la tabla esta vacía no tengo problemas, ya que con Pentaho quito los duplicados de los origenes. El problema lo tengo si el dato ya se encuentra en la tabla de SQL, que el Pentaho me da error de clave primaria duplicada.

¿Hay alguna forma de evitar esto?

Muchas gracias!

Execute a process arguments with spaces

Need assistance with use of Execute a process transformation step in Kettle 5.3. Does anyone know how to handle the situation where an argument contains spaces. For example, if the argument contains the following:

//risokcmfsp001/data_fab/common/Extra/ETL/Conversions/Mass Analyzer Reports/AnalyzeX.exe

the error Cannot run program "//risokcmfsp001/data_fab/common/Extra/ETL/Conversions/Mass Analyzer Reports/AnalyzeX.exe": CreateProcess error=2, The system cannot find the file specified occurs.

If the spaces in "Mass Analyzer Reports" are removed leaving "MassAnalyzerReports", the Execute process step runs good. I have tried enclosing with single and double quotes and brackets without any success.

Would appreciate any help.

Hello Group,

I am trying to call some transformation from a Java code by setting up input message.The code snippet is below

String msg = "random message"
try {
KettleEnvironment.init();
TransMeta metaData = new TransMeta("Simple.ktr");
Trans trans = new Trans(metaData);
trans.setVariable("data", msg); //trans.setParameter("data", msg);
trans.execute(null);
trans.waitUntilFinished();

if (trans.getErrors() > 0) {
System.out.print("Error Executing transformation");
}
} catch (KettleException e) {

e.printStackTrace();
}

Can someone please help me understand the difference between setVariable vs setParameter. Also is there a best way I can pass the input to transformation from a Java code.

Thanks & Regards,
Santosh

I have been waiting for the 5.4 release for a bit now, it has several fixes in it which will help me.

I see on JIRA that it doesn't seem to have any blockers.

My conundrum is whether to push my 5.3 release to production (production is at 5.1) or whether to wait x days for 5.4.

Anyone have release gossip on 5.4? Just trying to avoid pushing 5.3 and a week later pushing 5.4 and annoying my grumpy IT manager.

I know I could build CI ... but that presents more problems.

Thanks!
