> 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}
