hongwu updated HAWQ-991:
------------------------
Description:
User should be able to use HAWQ Register utility to register HAWQ table
files/directories into a new HAWQ cluster so that the data can be copied from
one cluster to another, and the HAWQ catalog metadata is synchronized with
these HDFS HAWQ files.
The ask for this feature is basically to pass `hawq register` an input file (or
set of files) containing the last-known-good metadata that it can use to update
the portion of the catalog managing HDFS blocks. Prior to every new data load,
the user can leverage the `hawq extract` command to snapshot the metadata for
every table to protect against corruption / divergence.
> Add support for "HAWQ register" that could register tables by using "hawq
> extract" output
