------------------------------
Summary: Java union index serialization/deserialization is
incorrect
Key: AVRO-2006
URL: https://issues.apache.org/jira/browse/AVRO-2006
Project: Avro
Issue Type: Bug
Components: java
Affects Versions: 1.8.1
Reporter: Marian S
According to the specification "A union is encoded by first writing a long
value indicating the zero-based position within the union":
However in java implementation index is encoded as an int (which is 32 bits)
see:
https://avro.apache.org/docs/1.8.1/api/java/org/apache/avro/io/Encoder.html#writeIndex(int)
This causes inconsistencies betewwn diffrent languages, because for instance I
can't deserialize avro serialized with Java using Python, because Python
expects long (64 bits) as an index of an union.
