dongjoon-hyun edited a comment on issue #23468: [SPARK-26535][SQL] Parse literals as DOUBLE instead of DECIMALS URL: https://github.com/apache/spark/pull/23468#issuecomment-451701676 Hi, @mgaido91 and @gatorsmile . First of all, Hive starts to use `Decimal` by default. Also, this introduces TPCDS-H query result difference among Spark versions. We cannot do this. I'm -1 for this. ```sql hive> select version(); OK 3.1.1 rf4e0529634b6231a0072295da48af466cf2f10b7 Time taken: 0.089 seconds, Fetched: 1 row(s) hive> explain select 2.3; OK STAGE DEPENDENCIES: Stage-0 is a root stage STAGE PLANS: Stage: Stage-0 Fetch Operator limit: -1 Processor Tree: TableScan alias: _dummy_table Row Limit Per Split: 1 Statistics: Num rows: 1 Data size: 10 Basic stats: COMPLETE Column stats: COMPLETE Select Operator expressions: 2.3 (type: decimal(2,1)) outputColumnNames: _col0 Statistics: Num rows: 1 Data size: 112 Basic stats: COMPLETE Column stats: COMPLETE ListSink ```
