> Key: HDFS-17216
> URL: https://issues.apache.org/jira/browse/HDFS-17216
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: distcp
> Affects Versions: 3.3.4
> Reporter: xiaojunxiang
> Priority: Major
> Attachments: DiscpAnalyze.jpg
>
>
> When distcp copies small files (file size slightly smaller than the
> bandwidth), the throbber only starts to throb after 1 second, and the
> throttled is specific to a single file. so the throbber becomes invalid,
> causing distcp to fill the cluster bandwidth and crush production traffic,
> which is a terrible thing.
