hongwu updated HAWQ-991:
------------------------
Issue Type: New Feature (was: Improvement)
> Add support for "HAWQ register" that could register tables by using "hawq
> extract" output
> -----------------------------------------------------------------------------------------
>
> Key: HAWQ-991
> URL: https://issues.apache.org/jira/browse/HAWQ-991
> Project: Apache HAWQ
> Issue Type: New Feature
> Components: Command Line Tools, External Tables
> Affects Versions: 2.0.1.0-incubating
> Reporter: hongwu
> Assignee: hongwu
> Fix For: 2.0.1.0-incubating
>
>
> 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.
