> When partitions are created using queries ("insert overwrite" and "insert
> into") then the StatsTask updates all stats. However, when partitions are
> added directly through metadata-only partitions (either CLI or direct calls
> to Thrift Metastore) no stats are populated even if hive.stats.reliable is
> set to true. This puts us in a situation where we can't decide if stats are
> truly reliable or not.
> We propose that the "fast stats" (numFiles and totalSize) which don't require
> a scan of the data should always be populated and be completely reliable. For
> now we are still excluding rowCount and rawDataSize because that will make
> these operations very expensive. Currently they are quick metadata-only ops.
