Thomas Scott created AVRO-1864:
----------------------------------
Summary: Decimal conversion should convert values with scale less
than intended scale instead of erroring.
Key: AVRO-1864
URL: https://issues.apache.org/jira/browse/AVRO-1864
Project: Avro
Issue Type: Bug
Affects Versions: 1.7.6
Reporter: Thomas Scott
Priority: Minor
Using Sqoop to import data to AVRO can mean that decimal scales in the incoming
values do not match the scales expected in AVRO. In this situation AVRO file
creation fails. However, in some cases this is not the correct behaviour, given
a value of 3.1 and a scale of 3 the value will fit into the scale requirements
and so should be adjusted.
Looking through the code this seems to be enforced here:
src/main/java/org/apache/avro/Conversions.java
public ByteBuffer toBytes(BigDecimal value, Schema schema, LogicalType type) {
int scale = ((LogicalTypes.Decimal) type).getScale();
if (scale != value.scale()) {
throw new AvroTypeException("Cannot encode decimal with scale " +
value.scale() + " as scale " + scale);
Should this not be:
if (scale < value.scale()) {
The same applies in: toFixed()
