Sergio Peña commented on HIVE-15199:
------------------------------------
Guys, [~ashutoshc], could you help me review the patch?
What it does is to use the alternative condition {{mvFile}} when the
destination filesystem is a blobstore. And, because this {{mvFile}} was calling
{{destFs.exists()}} for every file on S3, then I changed it to get a list of
files, and check whether the {{destf}} exists or not on that list.
> INSERT INTO data on S3 is replacing the old rows with the new ones
