[jira] [Created] (HIVE-26529) Fix VectorizedSupport support for DECIMAL_64 in HiveIcebergInputFormat

Rajesh Balamohan created HIVE-26529:
---------------------------------------

             Summary: Fix VectorizedSupport support for  DECIMAL_64 in HiveIcebergInputFormat
                 Key: HIVE-26529
                 URL: https://issues.apache.org/jira/browse/HIVE-26529
             Project: Hive
          Issue Type: Improvement
          Components: HiveServer2
            Reporter: Rajesh Balamohan


For supporting vectored reads in parquet, DECIMAL_64 support in ORC has been disabled in HiveIcebergInputFormat. This causes regressions in queries.

[https://github.com/apache/hive/blob/master/iceberg/iceberg-handler/src/main/java/org/apache/iceberg/mr/hive/HiveIcebergInputFormat.java#L182]

It will be good to restore DECIMAL_64 support in iceberg input format.
