Matt McCline commented on HIVE-19629:
-------------------------------------
The new line 403 in RecordReaderImpl does not look right. To convert from
DECIMAL_64 long to HiveDecimalWritable you should use the
HiveDecimalWritable.deserialize64 method that pass the long and the scale...
{noformat}
result.setFromLong(((Decimal64ColumnVector) vector).vector[row]);{noformat}
> Enable Decimal64 reader after orc version upgrade
