Hello together,
we try to ingest Avro-Events from Kafka to an MOR table on S3.
The Deltasteamer cannot validate our events, but they seem totally valid to
me. This is the error message:
```
org.apache.hudi.exception.SchemaCompatabilityException: Unable to validate
the rewritten record {"eventId": "test-eventId-prefix-tsw",
"happenedTimestamp": 6131449785280582000, "optionalField": null} against schema
{"type":"record","name":"TestEvent","namespace":"com.mycompany","fields":[{"name":"_hoodie_commit_time","type":["null","string"],"doc":""},{"name":"_hoodie_commit_seqno","type":["null","string"],"doc":""},{"name":"_hoodie_record_key","type":["null","string"],"doc":""},{"name":"_hoodie_partition_path","type":["null","string"],"doc":""},{"name":"_hoodie_file_name","type":["null","string"],"doc":""},{"name":"eventId","type":{"type":"string","avro.java.string":"String"}},{"name":"happenedTimestamp","type":{"type":"long","java-class":"java.time.Instant"}},{"name":"optionalField","type":["null",{"type":"long","java-class":"java.time.Instant"}],"default":null}]}

Im using hudi 0.5.3 on Spark 3.0.0 and avro 1.8.2 (I needed to patch this
commit into it:
https://github.com/apache/avro/commit/d9338a4cf008b445ea3efbe2523288d07162ec71).
Is the default value of null a problem?
Thanks a lot in advance!
Sebastian
The specific event (pretty printed):
```
{
"eventId": "test-eventId-prefix-tsw",
"happenedTimestamp": 6131449785280582000,
"optionalField": null
}
```
The avro-schema (pretty printed):
```
{
"type": "record",
"name": "TestEvent",
"namespace": "com.mycompany",
"fields": [
{
"name": "eventId",
"type": {
"type": "string",
"avro.java.string": "String"
}
},
{
"name": "happenedTimestamp",
"type": {
"type": "long",
"java-class": "java.time.Instant"
}
},
{
"name": "optionalField",
"type": [
"null",
{
"type": "long",
"java-class": "java.time.Instant"
}
],
"default": null
}
],
