Subject [jira] [Created] (HDFS-10313) Distcp does not check the order of snapshot names passed to -diff
Date Tue, 19 Apr 2016 21:44:25 GMT
Yongjun Zhang created HDFS-10313:
------------------------------------

             Summary: Distcp does not check the order of snapshot names passed to -diff
                 Key: HDFS-10313
                 URL: https://issues.apache.org/jira/browse/HDFS-10313
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: distcp
            Reporter: Yongjun Zhang


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.
