---------------------------------------
No resistance, just pointing out how it was worded. Not a committer on this
project, buy if you wanted to submit a PR I would guess it would be accepted.
> Error in AVRO specification
> ---------------------------
>
> Key: AVRO-3159
> URL: https://issues.apache.org/jira/browse/AVRO-3159
> Project: Apache Avro
> Issue Type: Bug
> Components: doc
> Reporter: Dave Cole
> Priority: Minor
>
> 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.
