Shilun Fan updated HADOOP-18567:
--------------------------------
Fix Version/s: 3.4.0
> LogThrottlingHelper: the dependent recorder is not triggered correctly
> ----------------------------------------------------------------------
>
> Key: HADOOP-18567
> URL: https://issues.apache.org/jira/browse/HADOOP-18567
> Project: Hadoop Common
> Issue Type: Bug
> Affects Versions: 3.3.4
> Reporter: Chengbing Liu
> Priority: Major
> Labels: pull-request-available
> Fix For: 3.4.0, 3.3.6
>
>
> The current implementation of {{LogThrottlingHelper}} works well most of the
> time, but it missed out one case, which appears quite common in the
> production codes:
> - if the dependent recorder was not suppressed before the primary one is
> triggered on the next period, then the next logging of the dependent recorder
> will be unexpectedly suppressed.
> {code:java}
> helper = new LogThrottlingHelper(LOG_PERIOD, "foo", timer);
> assertTrue(helper.record("foo", 0).shouldLog());
> assertTrue(helper.record("bar", 0).shouldLog());
> // Both should log once the period has elapsed
> // <pos1>
> assertTrue(helper.record("foo", LOG_PERIOD).shouldLog());
> assertTrue(helper.record("bar", LOG_PERIOD).shouldLog()); <--- This
> assertion will now fail
> {code}
> Note if we call {{helper.record("bar", LOG_PERIOD * 2)}} in <pos1>, as the
> existing test cases do, it will work as expected.
