> 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.
