Description

MESSAGE: InternalException: Required field 'row_tuples' was not present! Struct: TPlanNode(node_id:0, node_type:EMPTY_SET_NODE, num_children:0, limit:-1, row_tuples:null, nullable_tuples:null, compact_data:false, label:00:EMPTYSET, label_detail:, estimated_stats:TExecStats(cardinality:0, memory_used:0))

The query is:

select * from (select 10 as i, 2 as j, '2013' as s) as t where t.i < 10

Although this is a regression from 1.4, this seems like a corner case.
