----------------------------------
Summary: AvroTypeUtil Decimal support using Fixed Error
Key: NIFI-5662
URL: https://issues.apache.org/jira/browse/NIFI-5662
Project: Apache NiFi
Issue Type: Improvement
Components: Core Framework
Affects Versions: 1.7.1
Environment: RHEL 7.5
JDK 1.8.182
Reporter: Gideon Korir
When the decimal is specified as fixed in the Avro schema, AvroTypeUtils
converts the decimal into a ByteBuffer instead of a GenericFixed.
The code:
{code:java}
return new Conversions.DecimalConversion().toBytes(decimal, fieldSchema,
logicalType)
{code}
Should be:
{code:java}
return fieldSchema.getType() == Type.BYTES
? new Conversions.DecimalConversion().toBytes(decimal, fieldSchema, logicalType)
: new Conversions.DecimalConversion().toFixed(decimal, fieldSchema,
logicalType);
{code}
The former causes the AvroRecordSetWriter to fail with the error:
_org.apache.avro.file.DataFileWriter$AppendWriteException:
java.lang.ClassCastException: java.nio.HeapByteBuffer cannot be cast to
org.apache.avro.generic.GenericFixed_
