Istvan Fajth updated HIVE-23726:
--------------------------------
Description:
- Given:
metastore.warehouse.tenant.colocation is set to true
a test database was created as {{create database test location '/data'}}
- When:
I try to create a table as {{create table t1 (a int) location '/data/t1'}}
- Then:
The create table fails with the following exception:
{code}

Addtional info:
- The exception does not occur if I don't specify the location in the create
table statement
- 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.

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

> Project: Hive
> Issue Type: Bug
> Reporter: Istvan Fajth
> Priority: Major
>
> - Given:
> metastore.warehouse.tenant.colocation is set to true
> a test database was created as {{create database test location '/data'}}
> - When:
> I try to create a table as {{create table t1 (a int) location '/data/t1'}}
> - Then:
> The create table fails with the following exception:
> {code}
> org.apache.hadoop.hive.ql.metadata.HiveException:
> MetaException(message:java.lang.IllegalArgumentException: Can not create a
> Path from a null string)

> 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

> 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]
