---------------------------

             Summary: HiveServer2 - expose queryable data dictionary (ie 
Oracles' ALL_TAB_COLUMNS)
                 Key: HIVE-19919
                 URL: https://issues.apache.org/jira/browse/HIVE-19919
             Project: Hive
          Issue Type: New Feature
          Components: SQL
    Affects Versions: 2.3.2, 3.0.0
            Reporter: t oo


All major db vendors have a table like information_schema.columns, 
all_tab_columns or syscolumns containing table_name,column_name, data_type, 
col_order. Adding this feature to HiveServer2 would be very convenient for 
users.

This information is currently only available in the mysql metastore ie TBLS, 
COLS but should be exposed up into the HiveServer2 10000 port connection. Thus 
saving users from having 2 connections (1 to see data, 1 to see metadata). For 
security reason too, mysql can be firewalled from end-users.
