Config for key "layoutInfos" not found

KNIME Server
#1

Dear all,

I updated to knime analytics 4.1 and knime server to 4.10. I am trying to execute some workflows and I get the error below in the knime portal. I have already replaced old style wrapped metanodes with components and the legacy quick nodes with widgets. Although I cannot open the visual layout editor of the components (your operating system is using an outdated browser…update the libwebkit* packages, this is a separate issue) I have configured the components using the basic layout (only a couple of quickform nodes present). I get similar errors for the knime example workflows, such as 07_Visualize_Scatterplot_on_file.

Do you know what is going on?

Many thanks,

Panos

I realised the issue was the knime-server.config file was pointing to an earlier version of the knime platform (3.6). I changed this to point to the latest knime (4.1). No I am getting a different error hen loading a workflow

RMI executor could not be started, see log file for details

Looking at the knime server log file we have:

/srv/knime/knimeExecutor/knime_4.1.0/knime --launcher.suppressErrors --launcher.ini /srv/knime/knimeServer/knimeServerRepository/runtime/runtime_knime-rmi-50100/knime-rmi.ini
Last 5 lines of log output follow:
Knime:
A Java Runtime Environment (JRE) or Java Development Kit (JDK)
must be available in order to run Knime. No Java virtual machine
was found after searching the following locations:
plugins/org.knime.binary.jre.linux.x86_64_1.8.0.152-01/jre/bin
Also check log file in /srv/knime/knimeExecutor/knime_4.1.0/configuration

Which is strange because during the installation I pointed to the correct location of the openJDK bin folder.

I note that I installed manually knime analytics platform with the required server extensions in case this matters.

The configuration of the server seems valid, it is using the openJDK you configured during installation.

The knime executor of the server seems misconfigured. There is a knime.ini in /srv/knime/knimeExecutor/knime_4.1.0 that points to plugins/org.knime.binary.jre.linux.x86_64_1.8.0.152-01/jre/bin .

That was the location of the java binary of your knime executor 3.6., the new path has to be plugins/org.knime.binary.jre.linux.x86_64_1.8.0.202-b08/jre/bin .

Please change the path in the mentioned knime.ini ( and /config/knime.ini, if you use it) and restart the server afterwards, it should work.

Best Regards,

Dear all,

I would like to add some more information. It seems there is a java version mixup.

In particular:

  1. when I deployed knime server I used a specially downloaded java to avoid dependencies on the system java that may change by the system administrators. I installed
    $./java -version
    openjdk version “1.8.0_232”
    OpenJDK Runtime Environment (AdoptOpenJDK)(build 1.8.0_232-b09)
    OpenJDK 64-Bit Server VM (AdoptOpenJDK)(build 25.232-b09, mixed mode)

This is the java I pointed knime server installer to and the installation went fine.

  1. the system java is
    $ java -version
    openjdk version “1.8.0_222”
    OpenJDK Runtime Environment (build 1.8.0_222-b10)
    OpenJDK 64-Bit Server VM (build 25.222-b10, mixed mode)

  2. The error message in the knime server log complained that the knime executor could not find a java in
    path…/knimeExecutor/knime_4.1.0/plugins/org.knime.binary.jre.linux.x86_64_1.8.0.152-01/jre/bin

  3. In the knime executor we can find the following java

path…/knimeExecutor/knime_4.1.0/plugins/org.knime.binary.jre.linux.x86_64_1.8.0.202-b08/

So there are four versions of java involved here.

The java in 3. above came from a previous installation of knime server probably because I tried to reuse the old knime server repository. I created a new repository and manually copied the old workflows and this has fixed the issue.

Your Java configuration is valid. The server is running on the OpenJDK version you configured it to use and the KNIME Analytics Platform/Executor doesn’t need an external Java installation as it contains and uses the Open JRE in the plugins folder.

The path …/knimeExecutor/knime_4.1.0/plugins/org.knime.binary.jre.linux.x86_64_1.8.0.152-01/jre/bin was used by the old executor and is now misleading. The path shouldn’t exist anymore on your system after successfully upgrading the executor. This path in the knime.ini has caused the problem with the failing executor.

Is the server running now, are all your problems fixed?

Best Regards,

Michael
