> Hi,
> Avro spec says that writer schema's long can be promoted to reader
> schema's float or double.  In my test, I'm getting ErrorAction from
> ResolvingGrammarGenerator.generate() when writer schema is long and
> reader schema expects float.  Looking at the source code, when reader
> and writer type are not the same, the switch(readerType) only handles
> Long, Double and Union, not Float. This is the reason I'm getting "Found
> Long, expecting Float" error.
> Best regards,
> Xiaolu
