David Mollitor updated HIVE-22469: ---------------------------------- Attachment: (was: HIVE-22469.2.patch) > Lower Metastore DB Connection Pool Size in QTests > ------------------------------------------------- > > Key: HIVE-22469 > URL: https://issues.apache.org/jira/browse/HIVE-22469 > Project: Hive > Issue Type: Improvement > Components: Test, Tests > Affects Versions: 3.2.0 > Reporter: David Mollitor > Assignee: David Mollitor > Priority: Minor > Attachments: HIVE-22469.1.patch, HIVE-22469.2.patch, > HIVE-22469.3.patch > > > Hive Metastore uses the 'HikariCP' database connection pool. The default > number of connections to the database is 10. For the Qtests, connecting to a > local DerbyDB, there need not be more than 2 connections. Anymore simply adds > undo overhead and by looking at the QTest logs, I see a bunch of 'connection > refused' from HikariCP. It may be the case that the standalone DB does not > support that many concurrent connections anyway. > [https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-MetaStore] -- This message was sent by Atlassian Jira (v8.3.4#803005)
