ok, add one more service for all table names.
> [service] Hive API improvement
> ------------------------------
>
> Key: GRIFFIN-194
> URL: https://issues.apache.org/jira/browse/GRIFFIN-194
> Project: Griffin (Incubating)
> Issue Type: Sub-task
> Reporter: Nikolay Sokolov
> Priority: Minor
>
> Purpose is mainly to support GRIFFIN-195 with single request to get table
> list information, while avoiding transferring all table metadata and making
> lots of metastore requests.
> Hive API provides following relevant APIs right now:
> * listing DBs
> * getting all table names in DB
> * listing all table _objects_ in all _dbs_
> What's seems to be missing, is API call for all table names in all DBs (as
> middle ground between n+1 API requests and 1 API request with huge payload
> and n*m+1 metastore requests on backend).
> This api request should take no parameters, and return Map<String,
> List<String>> in response.
> Proposed API endpoint: TBD
