Hyunsik Choi commented on TAJO-1226:
------------------------------------
In the our roadmap, storage supports are changed to more pluggable. It would be
better if this kind of verification is each storage type. For it, we need
improved storage interface. I think that this issue should be done with the
interface that we have to design. So, I just rescheduled this issue to 0.11.
> LogicalPlanVerifier should check not supported type in file formats

> Fix For: 0.11
>
>
> *Problem*
> There are a variety of file formats in Hadoop eco systems. BTW, they have
> different type supports. For example, RCFile supports DATE type, but Parquet
> does not support DATE. Users can use not supported data types in a specified
> file format for writing tables.
> But, current Tajo does not check available data types for each file format.
> So, if a user specifies not supported types in his table for writing, a
> runtime error will occur while a query is running.
> *Solution*
> We should check not supported data type in logical plan verification phase.
