> 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.
