ProActive Scheduler

Sometimes a ClassCastException occur in the Resource Manager

Details

  • Description:
    Hide
    After submitting a Job_8_task, I get a ClassCastException in the RM console.
    It was not a critical exception as the RM still works normally after that.

    I was not able to reproduce the bug.


    Starting Resource Manager, Please wait...
    (Once started, press 'e' to shutdown)
    Resource Manager successfully created on pamr://3:-1/

    Exception in thread "Users pinger" java.lang.ClassCastException: org.objectweb.proactive.core.body.UniversalBodyRemoteObjectAdapter cannot be cast to java.lang.Comparable
            at java.util.TreeMap.put(TreeMap.java:542)
            at java.util.TreeSet.add(TreeSet.java:238)
            at java.util.AbstractCollection.addAll(AbstractCollection.java:305)
            at java.util.TreeSet.addAll(TreeSet.java:295)
            at org.ow2.proactive.resourcemanager.frontend.RMUserImpl$Pinger.run(RMUserImpl.java:347)

Bug was occuring when running over the new PAMR protocol. Here is an explanation of how to reproduce the bug :
1- Start a PAMR Router
$ ./startRouter.sh
... [addr=/138.96.218.202,localport=33647]

2- Add theses properties on the start of the RM, Scheduler, and Node
proactive.communication.protocol=pamr
proactive.net.router.address=138.96.218.202
proactive.net.router.port=33647

3- Start a node
$ ./startNode.sh node1
 ... pamr://0/node1 ...

4 - Start the RM
$ ./startRM.sh
 .... pamr://3/ ....
$ ./adminRM.sh -u pamr://3/

> addnode("pamr://0/node1","Default")
> listnodes()


5- Start the Scheduler
$ ./startScheduler.sh -u pamr://3/
 ... pamr://6:1099/ ...
$ ./adminScheduler.sh -u pamr://6/

> submit("/home/bamedro/Experimentations/AmazonEC2/scheduling/samples/jobs_descriptors/Job_8_tasks.xml")
> result(1)



Bug will occur in the RM core console window
