----------------------------------
Summary: Simple query with projection should be supported
Key: TAJO-1885
URL: https://issues.apache.org/jira/browse/TAJO-1885
Project: Tajo
Issue Type: Improvement
Components: TajoMaster
Reporter: Hyunsik Choi
Assignee: Hyunsik Choi
Fix For: 0.11.1
Tajo supports simple query as the following form:
{noformat}
select * from tb1
{noformat}
or
{noformat}
select * from tb1 LIMIT N
{noformat}
In many cases, users want to use some projections or functions like
{noformat}
select x,y,z from tb1 LIMIT N
{noformat}
This kind of queries are usually used to just see the data contents. Many users
expect that this query will return the result immediately. But, the simple does
not support this case. We need to support it.
