Miklos Szurap created HIVE-25879: ------------------------------------ Summary: 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
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. -- This message was sent by Atlassian Jira (v8.20.1#820001)
