Hey everyone, currently going through an upgrade from jppf 5.1.3 to 6.0. Migration for the most part has been good, running into a couple of issues/challenges

First here's the version I've deployed:

Code: [Select]

INFO  [2018-12-17 15:02:20,265] --------------------------------------------------------------------------------
INFO  [2018-12-17 15:02:20,265] JPPF Version: 6.0, Build number: 2240, Build date: 2018-10-06 09:32 CEST
INFO  [2018-12-17 15:02:20,265] starting node with PID=16592, UUID=C139E8FF-0046-0267-D5E8-274B970AFE01
INFO  [2018-12-17 15:02:20,265] --------------------------------------------------------------------------------

1.getAllJobIds management API is no longer available,  from what I can tell it's to be substituted with getAllJobUuids. However no such method exists the JMXDriverConnectionWrapper, still has getAllJobIds which throws the following exception:

Code: [Select]

javax.management.AttributeNotFoundException: No such attribute: AllJobIds

Possibly jppf client issue?


2. Consistently get java.lang.InterruptedException on existing call to see if driver is running.

Code: [Select]

try (JMXDriverConnectionWrapper jmxDriverConn = new JMXDriverConnectionWrapper("localhost", 11111)) {
            jmxDriverConn.connectAndWait(5000);

            if (jmxDriverConn.isConnected()) {
                          ......
            }
        } catch (Exception e) {
           ........................
        }
    }

This exception is swallowed with JPPF, never reaches the above catch block:

Code: [Select]

Any assistance would be greatly appreciated.

Hello CM!

Thanks once again for this detailed report.

Regarding the first problem: this is a mistake on our side, for which I registered the bug JPPF-567 JMXDriverConnectionWrapper.getAllJobIds still exists and raises an exception. Fortunately, there is an easy workaround:

Code: [Select]

JMXDriverConnectionWrapper jmx = ...;
String[] jobUuids = jmx.getJobManager().getAllJobUuids();
For the second problem, this is another bug: JPPF-568 Exceptions shown in the log when JMXDriverConnectionWrapper fails to connect to the driver. I guarantee that these exceptions are harmless, however I understand they can be an annoyance when showing up in the logs. The warning for InterruptedException can be hidden if you set the logging level to ERROR for the class org.jppf.comm.socket.QueuingSocketInitializer, whereas the other 2 exceptions can be hidden by setting the log level to INFO or above for the package org.jppf.management.

Sincerely,
-Laurent

Hi Laurent! Thank you so much for quick response!

Your suggestions worked perfect, again thank you!

Hi Laurent, is there a way to somehow hide those harmless errors in the logs?

Hello,

The bugs JPPF-567 and JPPF-568 were fixed in the JPPF 6.0.2 release. If you upgrade to this version, you shouldn't have the logs anymore. Could you please do that and let us know of the outcome?

Thanks,
-Laurent
