> We have multiple Oozie scheduled clusters. The problem that is currently 
> encountered is that some materialize queues are too late to process during 
> the peak hours of the scheduled tasks. We need to get the metrics of the 
> delay queue for alarm monitoring and adjust the configuration to optimize.
> Currently we have added metrics for queue size and latency in Oozie 
> CoordMaterializeTriggerService class, in order to reflect the general trend 
> of current scheduling.
