> Tasks send unnecessary Metrics and the repeated time is equal to the number
> of tasks in the executor, which runs them.
> Scenario: each time, a task will send repeated metric-tuples to the
> metricConsumer bolt (the 1st metric-tuple is normal, but the rest contain
> mostly zero-valued results).
> Causality: when a task receives a metric-tick-tuple, it "mistakenly" triggers
> all the tasks (belonging to the same executor) sending out metrics.
