> The following example shows the scenario where the current namespace is not
> respected:
> {code:java}
> sql("CREATE TABLE testcat.t USING foo AS SELECT 1 AS id")
> sql("USE testcat")
> sql("SHOW CURRENT NAMESPACE").show
> +-------+---------+
> |catalog|namespace|
> +-------+---------+
> |testcat| |
> +-------+---------+
> // `t` is resolved to `testcat.t`.
> sql("DESCRIBE t").show
> +---------------+---------+-------+
> | col_name|data_type|comment|
> +---------------+---------+-------+
> | id| int| |
> | | | |
> | # Partitioning| | |
> |Not partitioned| | |
> +---------------+---------+-------+
> // Now create a table under `ns` namespace.
> sql("CREATE TABLE testcat.ns.t USING foo AS SELECT 1 AS id")
> sql("USE testcat.ns")
> sql("SHOW CURRENT NAMESPACE").show
> +-------+---------+
> |catalog|namespace|
> +-------+---------+
> |testcat| ns|
> +-------+---------+
> // `t` is not resolved any longer since the current namespace `ns` is not
> used.
> sql("DESCRIBE t").show

> table.; line 1 pos 0;
