-------------------------------------
Summary: Add missing Javadoc enries to Interns.java
Key: HADOOP-13033
URL: https://issues.apache.org/jira/browse/HADOOP-13033
Project: Hadoop Common
Issue Type: Improvement
Components: metrics
Reporter: Andras Bokor
Assignee: Andras Bokor
Priority: Minor
Fix For: 2.8.0
Interns.java outputs "Metrics intern cache over flow" warn log for metrics
info/tag when the cache reaches the hard-coded limit and the oldest cache is
discarded for the first time. I'm thinking this log level can be changed to
info because
* there is no problem when the oldest cache is removed. if the metrics info/tag
is not in the cache, simply create it.
* we cannot configure the maximum size of the cache, so there is no way to stop
the warn log.
