Summary: RBF: Add top owners metrics for delegation tokens
Key: HDFS-15447
URL: https://issues.apache.org/jira/browse/HDFS-15447
Project: Hadoop HDFS
Issue Type: Improvement
Reporter: Fengnan Li
Assignee: Fengnan Li
Over time we have seen multiple times of token bombarding behavior either due
to mistakes or user issuing huge amount of traffic. Having this metric will
help figuring out much faster who/which service is owning these tokens and
stopping the behavior quicker.
