Subject Re: autoscaling is ignoring partiionMax
Date Wed, 28 May 2014 22:09:00 GMT
Hi Nirmal,

For some reason, that method is not getting called.  I've pasted my
stacktrace again with the drools methods removed:

---
Daemon Thread [Thread-56] (Suspended (breakpoint at line 137 in
CloudControllerClient))
owns: CloudControllerClient  (id=2433)
owns: DefaultAgenda  (id=2434)
   CloudControllerClient.spawnAnInstance(Partition, String, String,
String) line: 137
   RuleTasksDelegator.delegateSpawn(PartitionContext, String, String) line: 92
   //
   // drools methods hidden
   //
   AutoscalerRuleEvaluator.evaluateMinCheck(StatefulKnowledgeSession,
FactHandle, Object) line: 86
   ClusterMonitor.monitor() line: 99
   ClusterMonitor.run() line: 72
   Thread.run() line: 744
---

Would you expect to see AutoscaleAlgorithm.getNextScaleUpPartition
executed somewhere in the stack of calls?

Many thanks,

Chris
