Brock Noland commented on HIVE-4476:
------------------------------------
perhaps the use of checkForDefaultDb in that class just needs to be modified.
> HiveMetaStore caches the creation of a default db in a static way
> -----------------------------------------------------------------
>
> Key: HIVE-4476
> URL: https://issues.apache.org/jira/browse/HIVE-4476
> Project: Hive
> Issue Type: Improvement
> Affects Versions: 0.10.0, 0.11.0
> Reporter: Brock Noland
> Priority: Minor
>
> Currently HiveMetaStore.HMSHandler has a static flag set to true if the JVM
> has ever created a default db:
> https://github.com/apache/hive/blob/trunk/metastore/src/java/org/apache/hadoop/hive/metastore/HiveMetaStore.java#L176
> However, when testing it's nice to be able to create multiple HiveMetastore
> instances in a single JVM. Perhaps we should add a flag
> "hive.metastore.always.create.default.db" or something similar.
