[jira] [Commented] (AVRO-2520) Schema parsing does not work for non-record types with logicalType

["Ryan Skraba (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/AVRO-2520?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16914409#comment-16914409 ] 

Ryan Skraba commented on AVRO-2520:
-----------------------------------

I don't think this is related to logical types.  Is it possible that you are looking for :

{code}
new Schema.Parser().parse(" {\"type\": \"long\", \"logicalType\": \"MY_TIMESTAMP\" }")
{code}

If you just want the plain, non-record datum, this would be the way to go.

> The complex type cannot be properly parsed because it is not a simple string but a JSON object. Hence when calling `jsonNode.textValue()` the result is null. Check `getOptionalText(...)` for more information.
> When supplying logical types it should be possible to parse a simple schema.
