> in [parquet_analyze.q|https://github.com/apache/hive/blob/master/ql/src/test/queries/clientpositive/parquet_analyze.q#L27],
we need run "ANALYZE TABLE parquet_create_people COMPUTE STATISTICS noscan" to update the
statistic. 
> In [orc_analyze.q|https://github.com/apache/hive/blob/master/ql/src/test/queries/clientpositive/orc_analyze.q#L45],
we need not do that if we set hive.stats.autogather as true.
