Quanlong Huang commented on IMPALA-8797: ---------------------------------------- [~bharathv], [~vihangk1] Do you know how to let Hive3 show the "sys" and "information_schema" databases? They are not shown in the minicluster by default. There are few documents about this feature... > Blacklist "sys" and "information_schema" databases from Hive > ------------------------------------------------------------ > > Key: IMPALA-8797 > URL: https://issues.apache.org/jira/browse/IMPALA-8797 > Project: IMPALA > Issue Type: Improvement > Components: Catalog, Frontend > Affects Versions: Impala 3.2.0 > Reporter: bharath v > Assignee: Quanlong Huang > Priority: Critical > > HMS exposes these two databases "sys" and "information_schema" which contain > tables that expose the underlying meta information in a queryable format. > However, Impala cannot read them because they come with custom serde that > Impala doesn't support. > From a usability point of view, we should black list those databases from > loading, so that users don't see them when querying the database list. I > think that is reasonable because they can't query them anyway. -- This message was sent by Atlassian Jira (v8.3.2#803003) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-all-unsubscr...@impala.apache.org For additional commands, e-mail: issues-all-h...@impala.apache.org
