[jira] [Created] (HADOOP-13033) Add missing Javadoc enries to Interns.java

Andras Bokor created HADOOP-13033:
-------------------------------------

             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.
