> - 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.
