> limit does not work if applied to outer most block and it is not a query
> For eg
> insert into T1 select ... from T2 limit 10;
> will be executed as a map-job only.
> which means that the total number of rows in T1 is bounded by 10 * number of
> mappers.
> We need another map-reduce job to fix this or the move task needs to be
> modified.
> For now, the simpler fix of another map-reduce job should be ok, in future we
> can further optimize it by modifying the move task
