[jira] [Commented] (AVRO-1146) Can't use ReflectData to get schema when the type has a BigDecimal or BigInteger field

["Doug Cutting (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/AVRO-1146?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13448932#comment-13448932 ] 

Doug Cutting commented on AVRO-1146:
------------------------------------

I'd prefer we address this as follows:
 - Remove references to java.lang.Number, since Avro cannot correctly handle all subclasses.
 - Add a mechanism to declare that an arbitrary class is Stringable.
 - Use that mechanism to declare BigDecimal, BigInteger and other concrete Number subclasses.

I'll work on a patch that does this.

> I'm using avro Reflection API for a specific use case and I have a bug where if the object I'm trying to get the Schema for has a field of type BigDecimal. Because BigDecimal extends java.lang.Number, we try to create a primitive schema for it but fail doing so with the following error:
> *{{org.apache.avro.AvroRuntimeException: Not a Specific class: class java.math.BigDecimal}}*
> I'm attaching a unit test that shows the problem with a basic type that has a single BigDecimal field.
> This basically also applied to all subclasses of java.lang.Number that are not primitives.
