Labels: pull-request-available (was: )
> MetaStoreDirectSql test query should not query the DBS table
> ------------------------------------------------------------
>
> Key: HIVE-25879
> URL: https://issues.apache.org/jira/browse/HIVE-25879
> Project: Hive
> Issue Type: Bug
> Reporter: Miklos Szurap
> Assignee: Miklos Szurap
> Priority: Major
> Labels: pull-request-available
> Time Spent: 10m
> Remaining Estimate: 0h
>
> The runTestQuery() in the
> org/apache/hadoop/hive/metastore/MetaStoreDirectSql.java is using a test query
> {code:java}
> select "DB_ID" from "DBS"{code}
> to determine whether the direct SQL can be used.
> With larger deployments with many (10k+) Hive databases it would be more
> efficienct to query a small table instead, for example the "VERSION" table
> should always have a single row only.
