Todd Lipcon created HADOOP-8757: ----------------------------------- Summary: Metrics should disallow names with invalid characters Key: HADOOP-8757 URL: https://issues.apache.org/jira/browse/HADOOP-8757 Project: Hadoop Common Issue Type: Improvement Components: metrics Affects Versions: 2.0.0-alpha, 3.0.0 Reporter: Todd Lipcon Priority: Minor
Just spent a couple hours trying to figure out why a metric I added didn't show up in JMX, only to eventually realize it was because I had a whitespace in the property name. This didn't cause any errors to be logged -- the metric just didn't show up in JMX. We should check that the name is valid and log an error, or replace invalid characters with something like an underscore. -- This message is automatically generated by JIRA.
