[jira] [Created] (DRILL-1528) Update HiveRecordReader to read Hive decimal fields with scale and precision

Venki Korukanti created DRILL-1528:
--------------------------------------

             Summary: Update HiveRecordReader to read Hive decimal fields with scale and precision
                 Key: DRILL-1528
                 URL: https://issues.apache.org/jira/browse/DRILL-1528
             Project: Apache Drill
          Issue Type: Improvement
          Components: Storage - Hive
    Affects Versions: 0.6.0
            Reporter: Venki Korukanti
            Assignee: Venki Korukanti


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.
