Chaoyu Tang created HIVE-11964: ---------------------------------- Summary: RelOptHiveTable.hiveColStatsMap might contain mismatched column stats Key: HIVE-11964 URL: https://issues.apache.org/jira/browse/HIVE-11964 Project: Hive Issue Type: Bug Components: Query Planning, Statistics Affects Versions: 1.2.1 Reporter: Chaoyu Tang Assignee: Chaoyu Tang
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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
