bug fix: task metric send repeatedly
----
> task metric send repeatedly
> ---------------------------
>
> Key: STORM-326
> URL: https://issues.apache.org/jira/browse/STORM-326
> Project: Apache Storm (Incubating)
> Issue Type: Bug
> Affects Versions: 0.9.2-incubating, 0.9.1-incubating, 0.9.0.1
> Environment: CentOS 6.4 x64
> Reporter: troy ding
> Labels: metrics
> Attachments: executor-metrics.patch
>
> Original Estimate: 1h
> Remaining Estimate: 1h
>
> 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.
