ResourceBundle lookup during counter name resolution takes a lot of time ------------------------------------------------------------------------
Key: MAPREDUCE-2855 URL: https://issues.apache.org/jira/browse/MAPREDUCE-2855 Project: Hadoop Map/Reduce Issue Type: Bug Affects Versions: 0.23.0 Reporter: Todd Lipcon Assignee: Todd Lipcon Loading a job status page in trunk takes a lot of time, and it seems like most of the time is spent resolving counter names. Looking through the JDK source, ResourceBundle.getBundle(String) ends up calling getClassContext() which is not very efficient. I think if we pass our own classloader manually it will be faster. In Counters.incrAllCounters, we may also be able to avoid setting the counter name if one is already set. -- This message is automatically generated by JIRA.
