> Key: HDFS-15447
> URL: https://issues.apache.org/jira/browse/HDFS-15447
> Project: Hadoop HDFS
> Issue Type: Improvement
> Reporter: Fengnan Li
> Assignee: Fengnan Li
> Priority: Major
>
> 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.
