> The staging directory for inserts is always in the table root directory, but this may be a problem for partitioned external tables where external partition directories may be in a different encryption zone from the staging directory. In that case, the move operation will fail. We should fix this by placing the staging directories in the partition directory so that a copy between zones is not required.
