writer throws Working with nested fields
alphairys opened a new issue #1034: Datasource writer throws Working with nested fields
URL: https://github.com/apache/incubator-hudi/issues/1034
**Issue**
I have a dataframe with the following schema that I would like to write out as a hudi table.
**Schema**
```
root
|-- deviceId: string (nullable = true)
|-- eventTimeMilli: long (nullable = true)
|-- location: struct (nullable = true)
| |-- latitude: double (nullable = true)
| |-- longitude: double (nullable = true)
```
**Write out to hudi table:**
```
simple.write.format("org.apache.hudi")
.option(DataSourceWriteOptions.RECORDKEY_FIELD_OPT_KEY, "deviceId")
.option(DataSourceWriteOptions.PRECOMBINE_FIELD_OPT_KEY, "eventTimeMilli")
.option(HoodieWriteConfig.TABLE_NAME, hudiTableName)
.mode(SaveMode.Append)
.save(hudiTablePath)
```
Running this, i get the following error:
```
Caused by: org.apache.avro.UnresolvedUnionException: Not in union [{"type":"record","name":"location","namespace":"hoodie.hudi_test.hudi_test_record","fields":[{"name":"latitude","type":["double","null"]},{"name":"longitude","type":["double","null"]}]},"null"]: {"latitude": 34.7027, "longitude": 137.54862}
