Failure: clean install of 2.12 with server 4.1 on CentOS 6 [SOLVED]

[unknown_user]

I’ve done a clean install of 2.12 with server 4.1 on CentOS 6. The install scripts showed no errors. The server doesn’t work. The web interface shows but:

1. The web interface hangs when you try to view a (default) workflow
2. The server refuses a connection from a KNIME client when attempt to add a mount point (using KNIME Explorer - > new in the Preferences of KNIME).

Here’s a bit more information:

For the first problem, spaces in the default config may be a problem. (See below.)

In the localhost log file, I have this, apparently from visiting the web interface. I confirmed that the path is valid. So, I’m wondering if this is because of spaces in the path.

For the second problem, I get all sorts of exceptions in the catallina log. (See below).

I appreciate suggestions on fixing these.

If the WebPortal works but you cannot open any workflows then there is a problem starting the RMI instance that executes workflows. The localhost log file shows information messages when the RMI instance is being started and if something goes wrong.

Which address are you using for connecting to the server from the KNIME Client?

Your catalina logs doesn't show any exceptions, they are all information messages (at least the part that you posted above).

The SEVERE message in the localhost log file only show during the first startup because the metainformation for the repository root is missing. Default values will be used and written to disc.

I don't see any message related to spaces in paths in your post.

Thank you for your assistance!

It seems that I had more than on instance of tomcat running. I’ve fixed that, but still have an error.

If I just focus on the web interface after, to address the RMI issue you mention, then I see the following localhost log. (To me, it appears to have errors.)

[unknown_user]

If I just focus on connecting from a KNIME (eclipse) client to the server, this is what occurs.

When I edit New in KNIME Explorer, I add a KNIME ServerSpace connection with ID/Password to host.domain.edu (I use the real hostname). Then, KNIME (eclipse) client shows the ConnectException error (see below). I did not notice any errors in the server log files.

I have ports 8080 and 3700 open to connections. In any case, I run the KNIME client from the server.

Any ideas?

KNIME (eclipse) client

[thor]

Concerning the startup of the RMI instance: there are permission denied messages in the localhost.log which means that the user running the server doesn't have write permissions to the server repository directory. Please check the permissions, especially on the "runtime" folder.

When connecting to a 4.x server you have to use a different address scheme than for the 3.x (see also the installation and user manual). You have to use http://hostname:port/tomee/ejb. Please make sure that you use the correct port. The default is 8080 for http and 8443 for https.

[unknown_user]

I still can't connect the client to the server. (BTW, I have the setup working on a Windows server, using an earlier version of KNIME.)

[unknown_user]

I can connect to the server via the KNIME (Eclipse) client!

Sorry to be so dense. I missed the new setup connection: use http://hostname:port/tomee/ejb.

I still have the issue that the WebPortal does not show a workflow. It lists them.However, when I select one, it hangs. It seems like it is missing server-side scripting components.

In any case, thanks again for walking me toward the answer for the server conneciton. :-)

[thor]

The workflow loading issues can also be related to the permission issues seen in your log files.

[unknown_user]

After a complete new install, I have the same issues:

1. The web portal hangs when I attempt to access a workflow (as admin)
2. The Eclipse client can download and display a workflow. However, remote execution simples hangs, waiting for server to load the workflow.

The install scripts ran without error. I’ve attached the logs generated immediately after fresh install and attempts to do 1 and 2 above. I’m wondering if this is some CentOS SELinux sort of issue. Your suggestions will be greatly appreciated.

The server itself is running correctly. If you cannot execute workflows then there is a problem with the KNIME executor. You should check the knime.log from the runtime folder in this case (see also the installation manual).

[unknown_user]

I've confirmed that the executor is running. There are no log files in /srv/knime_server/runtime/runtime_knime-rmi-* folders. In runtime_knime-rmi-50100, there is only knime-rmi.ini and wekafiles (directory). There's no .metadata folder.

[unknown_user]

Sorry, I spoke too soon. After restarting, there is a .metadata directory. There log there looks good. However, the executor is still unresponsive. Here are the last lines of the knime.log from the runtime:

[unknown_user]

It seems to me that a connection is established between the sever and the executor. I see that with the first client request the server starts the RMI executor. But, that seems to be where the execution stops. I don't see the request to execute the workflow being passed onto the RMI exectuor. (Maybe it's not logged.)

Here’s the result of watch the process connection using netstat -plant | grep -i 50100:

Immediately after requesting an execution of a workflow:

tcp 0 0 :::50100 :::* LISTEN 10601/java

tcp 0 0 ::ffff:127.0.0.1:50100 ::ffff:127.0.0.1:54065 ESTABLISHED 10601/java

tcp 0 0 ::ffff:127.0.0.1:54065 ::ffff:127.0.0.1:50100 ESTABLISHED 10333/java

After a minute of “waiting for the server to load the workflow”

tcp 0 0 :::50100 :::* LISTEN 10601/java

tcp 0 0 ::ffff:127.0.0.1:54065 ::ffff:127.0.0.1:50100 TIME_WAIT -

After about 5 minutes:

tcp 0 0 :::50100 :::* LISTEN 10601/java

After about 7 minutes and thereafter:

tcp 0 0 :::50100 :::* LISTEN 10601/java

tcp 0 0 ::ffff:127.0.0.1:54073 ::ffff:127.0.0.1:50100 TIME_WAIT -

From ps, 10601 is the knime executor:

tomcat 10601 4.2 1.3 4002628 438700 pts/2 Sl 08:52 0:13 /opt/knime/jre/bin/java -XX:MaxPermSize=256m –server

From ps, 10333 is the knime server:

tomcat 10333 3.6 2.1 14189452 695380 pts/2 Sl 08:51 0:15 /usr/bin/java -Djava.util.logging.config.file=/opt/apache-tomee-plus-1.7.1/conf/logging.properties

[unknown_user]

I"ve done another reinstall after changing java to Oracle 8. It seems that the tomcat server does not communicate with the KNIME executor. It's still not working, nor is the WebPortal. I'm curious if KNIME 4.1 is working on a CentOs.

[unknown_user]

The primary reason this failed was that the RMI request was going through the firewall, which blocked it. If you ping $(hostname) and don't get 127.0.0.1, then the request will not pass the default iptables rule for the localhost interface. One fix is to edit /etc/hosts to include the hostname.

A second reason this coudl have failed was that I orignally used the default java (jre, jdk) for CentOS, which was open jdk. I switched to Oracle's Java 8.

It works now.

Thanks for the help thor!

[thor]

Whether you are using OpenJDK or Oracle JDK doesn't matter. But the Firewall may indeed by the cause of the problem.
