-----------------------------------------------------------------

This is not an error. 0x02 is the zigzag variable width encoding of index 1.

 

The italicized "int" is meant to refer back to how integers are handled in avro.

> On [http://avro.apache.org/docs/current/spec.html#binary_encode_primitive] the example given for encoding Unions appears to have an error:
> {quote}For example, the union schema ["null","string"] would encode:
> null as zero (the index of "null" in the union):
> 00
> the string "a" as one (the index of "string" in the union, encoded as hex 02), followed by the serialized string:
> 02 02 61
> {quote}
> Surely the "string" in the union is encoded as hex 01...  It is defined as "the zero-based position within the union of the schema".  The list has only two entries, so 02 is not a valid index.
