> - The exception does not occur if I specify the managedlocation as well in the create database statement.
> - If I do not specify any location for the database then I can not point the external table to an arbitrary directory and can not use external files to load data into a managed database via Hive easily this is especially a problem if I have an external data source on something else then HDFS, and want to pull the data into Hive.

> - The code where the exception occurs is [the following line|https://github.com/apache/hive/blob/7cdf362f9f1a53025b371a8d5122336ded71d692/standalone-metastore/metastore-server/src/main/java/org/apache/hadoop/hive/metastore/MetastoreDefaultTransformer.java#L802]:
> {code}
> dbLocation = Path.getPathWithoutSchemeAndAuthority(new Path(db.getManagedLocationUri()));
> {code}
> it seems that the db.getManagedLocationUri() gives back a null reference for the test table. Metastore debug log does not contain the managed location, so I can not confirm this based on the logs, it would be nice as part of the fix to add the managedlocation used for the path validation of the table as well to the [debug log here|https://github.com/apache/hive/blob/7cdf362f9f1a53025b371a8d5122336ded71d692/standalone-metastore/metastore-server/src/main/java/org/apache/hadoop/hive/metastore/MetastoreDefaultTransformer.java#L792] also.
