Summary: Separate string metric from tag in hadoop metrics2
Key: HADOOP-17604
URL: https://issues.apache.org/jira/browse/HADOOP-17604
Project: Hadoop Common
Issue Type: Improvement
Components: common
Reporter: Fengnan Li
Assignee: Fengnan Li
Attachments: Screen Shot 2021-03-26 at 2.50.08 PM.png
Right now in hadoop metrics2, String metrics from method are categorized as tag
(v.s. metrics as other number types), this caused later when reporting beans,
it will add a prefix "tag." before the metric name.
It will be cleaner if we have another child inherit MutableMetric for string
(maybe MutableText?) thus the String metrics from method can get rid of the tag.
