Summary: Add exponential weighted moving average in metrics2.util
Key: HADOOP-12335
URL: https://issues.apache.org/jira/browse/HADOOP-12335
Project: Hadoop Common
Issue Type: Improvement
Components: metrics
Reporter: Xianyin Xin
Assignee: Xianyin Xin
Sometimes we need to collect the average value of a variable, but for variables
that is time related, the more recent value is more important. For example, we
want to see the average container allocation rate in the last 5 min.
Exponential weighted moving average is a solution for this scenario.
