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.

> Key: AVRO-2520
> URL: https://issues.apache.org/jira/browse/AVRO-2520
> Project: Apache Avro
> Issue Type: Bug
> Components: java
> Affects Versions: 1.9.0
> Reporter: Teodor Kostov
> Priority: Minor
>
> Parsing the following schema fails:
> {code:java}
> new Schema.Parser().parse("{ \"name\": \"test\", \"type\": { \"type\":
> \"long\", \"logicalType\": \"MY_TIMESTAMP\" }}")
> {code}
> with the following exception:
> {noformat}
> No type: {"name":"test","type":{"type":"long","logicalType":"MY_TIMESTAMP"}}
> org.apache.avro.SchemaParseException: No type:
> {"name":"test","type":{"type":"long","logicalType":"MY_TIMESTAMP"}}
> at org.apache.avro.Schema.getRequiredText(Schema.java:1725)
> at org.apache.avro.Schema.parse(Schema.java:1576)
> at org.apache.avro.Schema$Parser.parse(Schema.java:1366)
> at org.apache.avro.Schema$Parser.parse(Schema.java:1354)
> {noformat}
> 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.
