troy ding created STORM-326:
-------------------------------
Summary: 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
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.
