> Currently, Tajo uses {{tajo.warehouse.directory}} to a default tablespace.
> The default tablespace is stored to catalog server when TajoMaster starts up
> firstly.
> Some users can change {{tajo.root}} after they use Tajo for a while. In this
> case, the mismatch between {{tajo.root}} and the default space can cause some
> problems. To avoid this confusion, we need to support {{ALTER TABLESPACE}} to
> change tablespace's URI.
> The semantic is as follows:
> {code}
> ALTER TABLESPACE <space name> LOCATION '...';
> {code}
