By following this it resolved the Error for
SecondDerivativeFinderWindowProcessor. But I am getting following errors
now for AverageHeathRequest and AverageInFlightRequestsFinder execution
plans.

Re: [Dev] [CEP 3.1.0] Syncing failed when becoming a Passive Node for tenant

2015-09-18 Thread Akila Ravihansa Perera 
Hi Tishan,
Anuruddha and I went through the Siddhi-core 2.1.0 code and noticed that
TimeBatchWindowProcessor class has the same issue in restoreState method
[1]. What is the impact of this error "Syncing failed when becoming a
Passive Node"?

[1]
http://svn.wso2.org/repos/wso2/carbon/platform/branches/turing/dependencies/commons/siddhi/2.1.0-wso2v1/modules/siddhi-core/src/main/java/org/wso2/siddhi/core/query/processor/window/TimeBatchWindowProcessor.java

Thanks.

Re: [Dev] [CEP 3.1.0] Syncing failed when becoming a Passive Node for tenant

2015-09-17 Thread Tishan Dahanayakage 
Hi All,

I remote debugged this and found out why this is occurring. The issue is
when we are building the Siddhi configuration We set
'DistributedProcessing' by checking whether ExecutionPlanConfiguration
returns "true" for the property  "siddhi.enable.distributed.processing".

if (isDistributedProcessingEnabledString != null &&
isDistributedProcessingEnabledString.equalsIgnoreCase("true"))

When we set distributed mode as Redundant node when creating the execution
plan property  "siddhi.enable.distributed.processing" returns
"RedundantNode". Hence distributed processing in Siddhi configuration is
not set. I am not quite sure whether this is the intended behavior.

Then in the init method of custom time window they initialize the window as
follows.


if (this.siddhiContext.isDistributedProcessingEnabled()) {
window = new SchedulerSiddhiQueueGrid(elementId, this,
this.siddhiContext, this.async);
} else {
window = new SchedulerSiddhiQueue(this);
}

SchedulerSiddhiQueue restore method expects a LinkedBlockingQueue. Hence
the ClassCastException. This means we are receiving a wrong object for the
restore method. And this happens on second node start up. Do we share state
between two execution plans through currentState/restoreState?

Thanks
Tishan

@Anuruddha: Will us be able to debug this method in the second CEP node and
see the type of the data object being passed? It would be better if we can
also get siddhi source code attached.

Other question is do we need to migrate this logic?

Re: [Dev] [CEP 3.1.0] Syncing failed when becoming a Passive Node for tenant

2015-09-17 Thread Tishan Dahanayakage 
Hi Anuruddha,

As discussed offline issue is with window.restoreState((Object[]) data[0]);
line. Underlying window implementation(SchedulerSiddhiQueue) is expecting a
object[] for its restore method and cast its first element
to LinkedBlockingQueue. But we are sending first element itself again after
sending object[] earlier. So having only window.restoreState(data); will
work fine.

Thanks
Tishan

 Hi,

 I created CEP HA cluster with Deployment for full-active-active mode
 as per [1].
 I am seeing following error when starting the 2nd member.
 I have also attached execution plan [2].

 What is causing this issue ?
