[~zuston] For me, the test error looks related, your new test case fails. Could
you please check it.

> 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.
