> Key: HDFS-10313
> URL: https://issues.apache.org/jira/browse/HDFS-10313
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: distcp
> Reporter: Yongjun Zhang
> Assignee: Lin Yiqun
>
> This jira is to propose adding a check to distcp, when {{-diff s1 s2}} is
> passed, we need to ensure that s2 is newer than s1, otherwise, abort with a
> informative error message.
> This is the result of my offline discussion with [~jingzhao] on HDFS-9820.
> Thanks Jing.
