Akira AJISAKA created HADOOP-12822: -------------------------------------- Summary: Change "Metrics intern cache overflow" log level from WARN to INFO Key: HADOOP-12822 URL: https://issues.apache.org/jira/browse/HADOOP-12822 Project: Hadoop Common Issue Type: Improvement Components: metrics Reporter: Akira AJISAKA Priority: Minor
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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
