> Currently HiveRecordReader reads decimal data in Hive and converts to VarChar. The reason is: Hive-0.12 doesn't enforce same precision and scale for all records. Drill may get records with different precision and scale within a column which Drill can't handle it currently. In Hive-0.13 scale and precision are enforced for all records in a column. As DRILL-1347 upgrades Hive storage plugin to work with Hive-0.13, this JIRA is created to track changes to HiveRecordReader to read Hive decimal data as decimal and not as VarChar.
