Loading hierarchy of objects to DB knowing patterns to match

February 24, 2016, 7:17 am
$

I have a set of information that's going into a DB table.
Now I need to build up information about their hierarchy (parents) using some constraints and database sequence column.

case length substring hierarchy.jpg

id_parent is the column to be created based on lookup in the same stream involving info_lokalizacja substring match (presented as rectangles in different colors to show the lookup).

Based on length of string in column info_lokalizacja I need to select id_db_seq from the same stream where a substring of that info_lokalizacja column would match entire value.
This is a typical child-parent implementation.
I could probably duplicate the stream and do this all within Java Script, but I'm not sure if that's the best approach. I consider JS coding to be the last thing to do in Kettle, when there are no steps to achieve the task.

I basically need to implement something that would be equivalent to below SQL.

Code:
INSERT INTO table(...)
  SELECT
    id,
    CASE
      WHEN length(info_lokalizacja) = 4 THEN null
      WHEN length(info_lokalizacja) = 7 THEN (select id from table2 where info_lokalizacja = left(info_lokalizacja, 4))
      WHEN length(info_lokalizacja) = 11 THEN (select id from table2 where info_lokalizacja = left(info_lokalizacja, 7))
      END AS id_parent
  FROM
    table2;
I can think of some solutions but I bet they would be involving too much overhead for the task, because I have more of such patterns and depending on the id_typ column I have to apply a different "CASE" hierarchy building logic, so creating new columns for all substrings for each row is not really a solution.

I'd be thankful even for the list of steps which I could use to accomplish the task. I do NOT ask for a complete solution.

Hi Sir,

MySQL,pdi-ce-6.0 file repository, Windows, Java 1.7 versions

Could you please suggest me how can i achieve issue like : "DOS format was specified but only a single line feed character was found, not 2 ? "

IF I use Table input --> Text file output then text placing into multiple rows. if i use function replace('term_des','\n', ' ') then i am getting single row.

select term_des from prod -- getting issue using this query
select replace(term_des,'\n',' ' ) from prod -- getting correct result using this query

sample text:

update entity_enttlmnt set term_description='Turbines, turbine shaft, bearings, internalvariable vane assembly, and turbocharger housing. Does not include: wiringharnesses, wastegates; oil, fuel, or coolant lines; external fittings, clamps, bolts,or fasteners, charge air cooler and duct work, injector seals, cups or tubes, EGRvalves and associated components, linkages, connectors, V Pod, actuators, seals &gaskets, vacuum controls or electrical components off(course))))$#'

how can i acheive this issue without replace function ? please suggest me if i need to change separator and enclosure settings in text file output step.

Open Referenced Object .. Transformation not working

February 24, 2016, 2:41 pm

Good afternoon,

We are trying to migrate our PDI jobs from Version 5.1 to 6.0.1. In our current environment we are using Windows Server 2008, Java 7 and storing all jobs and transformations on the file system.

In the new environment we want to use Centos7, OpenJDK 8 and go back to storing the job and transformation definitions in a MySQL database repository. We had previously used an Oracle database as our repository about 4 years ago which worked great with PDI 4.1 and 4.2

I moved a couple of jobs to the new server and database repository and was able to run them successfully. However, when I tried to open a transformation by right clicking on it in the Job and selecting Open Referenced Object > Transformation, nothing happens. I opened Spoon in debug mode and I can see the line:

Code:
Loading transformation from repository [DataWarehouseAlertProcess] in directory [/Alerts]
in SpoonDebug.txt. But there are no error mesages.

However, if I move the transformation to the root directory of the repository and point the transformation step at this new location, then select Open Referenced Object > Transformation works successfully. Obviously, I don't want to have all of my jobs and transformations saved at the root level.

Has anyone else experienced this?

Thanks,
Greg

Hey guys,

I'm starting to work with InfluxDB. However, in the Connection Type list the InfluxDB option is not available. So, I would like to know if there's a connector or some way to work with InfluxDB in Spoon.

Thanks! Sorry for the bad English.

Data with 40K+ rows

Hi all PDI experts,

I am new to PDI... hope you will be able to assist me.

What I am trying to do is to load the ServiceNow data into a PostgreSQL DB.

Steps:
  1. Generate Rows
  2. REST Client
  3. Get data from XML
  4. Select values
  5. Table output

There are over 40K+ incidents, when I tried loading the data, it only returned 10,000 records.
How could I load every single records?

My plan is to get all records for the first time at least, then insert/update records on the weekly basis (still finding a way to do it). Or is there any better way to do it?
The XML link is a URL, which does not allow me to set any time period on it. :confused:

Thank you everyone!!!

Changes to DB repository not committed

Hello all,

I have found a weird behavior when using a DB repository:

If I use the repository explorer and make some changes like e.g. moving a job to a folder or renaming a transformation, those changes are not committed to the repository UNLESS I disconnect the repository on purpose by using Tools -> Repository -> Disconnect Repository. They are not committed even if I quit Spoon.

I have confirmed this behavior using both mySQL and Postgres based repositories, so to me it doesn't look like an issue with one specific DB flavor.

My environment: PDI 6.0.1 with mySQL/Postgres repos running in an Ubuntu virtual box.

Can you confirm this issue and whether it will be resolved?

Thanks!

Hi all,

I'm trying to get Pentaho Map Reduce working in our corporate Cluster (CDH 5.4, with 6.01 Kettle and the approriate shim). The libraries get copied up to HDFS no Problem, and then in my user home I get a .staging Directory with a job_xyz subfolder containg Job.jar, Job.xml, jop.split and Job.splitmetainfo. There are no subdirectories in this Folder (e.g. lib). The application fails with the message :

Error: Could not find or load main class org.apache.hadoop.mapreduce.v2.app.MRAppMaster

It seems that somehow the required librares are not accessible. Does this sound familar to anyone out there?

Thanks.

CDA Datasource in CDE

I'm trying to build a dynamic dashboard that can deal with several different datasources, but I'd like to have to set those up on a CDA file only, kind of a plugCDA-and-play system. Also, I want each dashboard to view the datasources associated with it only, instead of all the ones I've got setup on pentaho.

As such, with the approach I'm taking, I need to be able to check which CDA files are defined on the dashboard's datasources, to then parse said files for the datasource connections that I should present to my users.

Can I access CDA data source path property somehow, while running?
How about modifying CDA data source data access ID, also while running?

Also, could you point me in the right direction as to how to fetch schema/cube data directly?

I am struggling to get the HTTP post implementation correct in the Pentaho. Initially I tried with the HTTP POST option. This is not at all working. Then I started trying with the REST CLIENT.

Can you kindly tell me what exactly meant By

- the BODY FIELD? In which format one have to use?
- What exactly is Parameters and Headers Tab?
Restclient_Settings_General.jpgTransformation.jpg
Can someone kindly help me here?
I am using the Generate Rows to read the URL and then it to REST CLIENT to read the JOSN file with POST request.

I will appreciate if someone can kindly send some links to working examples how to use the REST CLIENT with POST requests?

Regards,
Krishna

Understanding Merge Join

Hello All,

I wish to understand the Merge Join. I have two streams (say Stream A and B) of data with varying columns and I wish to pick few columns from Stream B after performing a join between two streams.

Reading the documentation, it asks for the columns of each streams to be sorted, however, my question is if there is additional data in either of the Streams, is the join performed sequentially?


Stream A

Col1|Col2|Col3
-------------------
C|D|2
A|A|4
A|B|1
E|F|3


Stream B
Col11|Col12|Col13
----------------------
P|Q|12
X|Y|13
A|B|11


With this example, I want my output to be


Col1|Col2|Col3|Col4
----------------------
A|A|4|(null)
A|B|1|11
C|D|2|(null)
E|F|3|(null)

I tried to use Merge Join (Left Outer) but the join for A|B does not work and always Col4 persists as Blank.

instaling report designer not connecting to mysql

I'm very new to pentaho but experienced with mysql & php. I have just recently set up PDI on my macbook air. PDI has a folder with a bunch of files, and the important lib/ folder in which I added the jar file to enable pentaho to talk to mysql. It's connecting just fine to mysql, and I've run some transformations. However Report Designer is not. Unlike PDI, RD appears on the mac to be a single file application, no file folders in finder. Can you tell me how do I either get Report Designer to recognize the existing jar file, or put a copy of it somewhere so it can use it to connect to mysql?
