  • 1.  Error from Concat fields in PDI CE 9.3.0.0-428

    Posted 05-23-2022 11:40
    Hello everyone,
      I have noticed that in PDI CE 9.3 (on Open jdk 8) the Concat Fields component throws an error if in the Advanced tab the option Fast data dump (no formatting) is unchecked. With such option unchecked it goes into error even if the Length of Target Field is provided (is not 0 but a large number).

    Did anyone experience the same or is it just working fine for you?
    Thanks,
     Antonio

    Hi Antonio

    I tried it on 93EE without a problem.

    Try running it using Azul OpenJDK11 instead of 8 ( add
    export JAVA_HOME=/Path/to/java11
    to the spoon.bat/command/sh file

    If that doesn't work, can you come back with the OS, and how long the fields you're concatenating are as well.

    Hi Andrew,
      Thank you for your reply. I tested a very simple transformation ( Generate rows -> Concatenate Fields -> Log ) on two test environments that I have and the results are:

    - on Linux, the test transformation works without problems on PDI CE 9.3 (even with AdoptOpenJDK 8)
    - on Windows 10 20H2 the test transformation fails on PDI CE 9.3 (with either AdoptOpenJDK 8 or Azul open Jdk 11)
    - on Windows 10 20H2 the test transformation works on PDI CE 9.2 (with AdoptOpenJDK 8).

    The total length of the strings that I'm trying to concatenate is short, 3 strings of less than 15 chars each.

    Below the pan output at Rowlevel log level from the failed attempt on Windows.

    Can you include your test transform?  I can surmize what you are doing from the log, but cannot reproduce it.   The fact that concat fields is giving a textFileOutput error is likley the clue.  No length specified in the field for output, but you are not using any textoutput steps yourself.

    I am not seeing any text output in my concat and even added a textfileoutput to the end of the stream without issues.
    Similar test worked on Windows 10 with OpenJdk 8_133.

    Hi Stephen,
     Thank you for taking the time and looking into this strange behavior.

    Please find attached the test transformation.

    I tried to run it from Spoon and from the command line using pan on Windows 10 with OpenJDK 11.0.15 and got the failure.

    As said, if I configure the Concat fields step by checking the "Fast data dump (no formatting)" checkbox, then it runs.

    Good new bad News.  Works just fine for me in 9.3 CE and EE.  Logging with row level detail is below.

    I believe that the call out to a TextFileOutput from within the concat rows step is still the clue.  Some change to the overall logging level, debug or somethign environmental?

    Thank you again for these tests Stephen.

    I'll try to better examine my environment.

    I need also to understand how the TextFileOutput call happens from the Concat Fields.
