t oo commented on HIVE-19919: ----------------------------- gentle ping > 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: 3.0.0, 2.3.2 > Reporter: t oo > Priority: Major > > 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. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
