TestMetricsSystemImpl.testMultiThreadedPublish fails intermediately
[ https://issues.apache.org/jira/browse/HADOOP-10468?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13962525#comment-13962525 ]
Haohui Mai commented on HADOOP-10468:
-------------------------------------
The problem is that the configuration value is not picked up in the unit test. Investigation shows that the {{MetricsConfig}} class converts the prefix into lowercase string, internally the prefix is used to look up the configuration value. The mismatch of letter cases causes the system fails to pick up the configuration values.

> {{TestMetricsSystemImpl.testMultiThreadedPublish}} can fail intermediately due to the insufficient size of the sink queue:
> {code}
> 2014-04-06 21:34:55,269 WARN impl.MetricsSinkAdapter (MetricsSinkAdapter.java:putMetricsImmediate(107)) - Collector has a full queue and can't consume the given metrics.

> {code}
> The unit test should increase the default queue size to avoid intermediate failure.
