--------------------------------
Hi [~xyao], [~ljain]
I see in the source code:
[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. It's not changed in the patched provided. So how will it
work when you launch a distcp job with diff parameter ?
Thanks.
