> RelOptHiveTable.hiveColStatsMap might contain mismatched stats since it was
> built by assuming the stats returned from
> ==
> hiveColStats =StatsUtils.getTableColumnStats(hiveTblMetadata,
> hiveNonPartitionCols, nonPartColNamesThatRqrStats);
> or
> HiveMetaStoreClient.getTableColumnStatistics(dbName, tableName, colNames)
> ==
> have the same order of the requested columns. But actually the order is
> non-deterministic. therefore the returned stats should be re-ordered before
> it is put in hiveColStatsMap.
