> [~ljain] has worked on the JIRA:
> https://issues.apache.org/jira/browse/HDFS-13052 to provide the possibility
> to make DistCP of SnapshotDiff with WebHDFSFileSystem. However, in the patch,
> there is no modification for the real java class which is used by launching
> the command "hadoop distcp ..."
>
> You can check in the latest version here:
> [https://github.com/apache/hadoop/blob/branch-3.1.1/hadoop-tools/hadoop-distcp/src/main/java/org/apache/hadoop/tools/DistCpSync.java#L96-L100]
> In the method "preSyncCheck" of the class "DistCpSync", we still check if the
> file system is DFS.
> So I propose to change the class DistCpSync in order to take into
> consideration what was committed by Lokesh Jain.
