Navis commented on HIVE-9397:
-----------------------------
CLI uses OI in fetch task to read rows, which is provided by StatsOptimizer.
But beeline uses schema in SemanticAnalyzer which is acquired from RR of final
FS. I think StatsOptimizer should not override return schema.
> SELECT max(bar) FROM foo is broken after ANALYZE ... FOR COLUMNS
