Kyle R Dunn commented on HAWQ-1011:
-----------------------------------
In the event of using register to "update" metadata about an existing table
(e.g. in the case of catalog / data inconsistency) - we need the ability to
overwrite the table's metadata in the catalog - meaning that table will also
already exists. If we have to "drop" from the catalog and re-register, the data
in HDFS will be dropped, which is not the desired behavior. Please discuss with
[~lei_chang] and [~vVineet] for clarification.
> Check whether the table to be registered is existed
