---------------------------------
Summary: ALTER TABLESPACE LOCATION support
Key: TAJO-755
URL: https://issues.apache.org/jira/browse/TAJO-755
Project: Tajo
Issue Type: Improvement
Components: catalog, parser, planner/optimizer
Affects Versions: 0.8-incubating, 1.0-incubating
Reporter: Hyunsik Choi
Assignee: Hyunsik Choi
Fix For: 0.8-incubating, 1.0-incubating
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}
