Review Comment:
From what I can guage, these are the supported types
```
private static boolean canCompare(Schema schema, HoodieRecordType
recordType) {
// if recordType is SPARK then we cannot compare RECORD and ARRAY types
in addition to MAP type
if (recordType == HoodieRecordType.SPARK) {
return schema.getType() != Schema.Type.RECORD && schema.getType() !=
Schema.Type.ARRAY && schema.getType() != Schema.Type.MAP;
}
return schema.getType() != Schema.Type.MAP;
}
```
