Quartz clustering in camel spring DSL - apache-camel

Question

I am trying to achieve "requests recovery" in fail-over scenario in two different machine with their clock also sync.
My configuration as below:
step 1: camel-context.xml
I have defined the below route in camel-context.xml file.
<route id="quartz" trace="true">
<from uri="quartz2://cluster/quartz?cron=0+0/2+++*+?&durableJob=true&stateful=true&recoverableJob=true">
<route>
step 2: quartz.properties:
I have enabled
org.quartz.jobStore.isClustered = true
org.quartz.scheduler.instanceId = AUTO
org.quartz.scheduler.instanceName =ClusteredScheduler
Currently I am running same camel application in two different instances in my local and clustering is working fine . But when I try to test the "requests recovery" I am getting below exception.
Exception :

After shutting down the instance1 which is currently excuting the job , instance 2 is trying to recover the job immediately but its failing to execute the job .It is picking the same job in next interval (which is fine).
My requirement is active node immediately recover the failed job.
Thanks in advance.

I think we can avoid the checking of ensureNoDupTriggerKey, if the recoverableJob is true. I just created a JIRA CAMEL-8076 for it.
