> The following query works ok.. it has an expression in the SELECT list and we are doing an ORDER-BY on that expression: 
> select N_NATIONKEY + 1 from dfs.`/tmp/parquet/nation.parquet` order by 1;
> However, the following query which puts the same expression in the ORDER-BY clause throws an error: 
> select N_NATIONKEY from dfs.`/tmp/parquet/nation.parquet` order by N_NATIONKEY + 1;
> Error 2935dcfa-2b22-45ea-b74f-05d0133a0608: Failure while parsing sql.
