-----------------------------------
Summary: When distcp handle the small files, the bandwidth
parameter of distcp will be invalid, resulting in serious overspeed behavior
Key: HDFS-17216
URL: https://issues.apache.org/jira/browse/HDFS-17216
Project: Hadoop HDFS
Issue Type: Bug
Affects Versions: 3.3.4
Reporter: xiaojunxiang
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.
