Anishek Agarwal commented on HIVE-23520:
----------------------------------------

[~rajesh.balamohan] not sure about the use case, can you explain in detail please. looks like you are skipping copy of the data to staging directory, but repl load will not work here since currently it only looks up data on the staging directory.

> Currently, "REPL DUMP" ends up copying entire dataset along with partition information, stats etc in its dump folder. However, there are cases (e.g large reference datasets), where we need a way to just retain metadata along with partition information & stats.
