> I want to toString() schemas and send them to the backend via UDFContext. At the moment
this requires writing your own toString() method that Utils.getSchemaFromString() can read.
Making a readable schema for the backend would be an improvement.
> I spoke with Thejas, who believes this is a bug. The workaround for the moment is, for
example:
> String schemaString = inputSchema.toString().substring(1, inputSchema.toString().length()
- 1);
> // Set the input schema for processing
> UDFContext context = UDFContext.getUDFContext();
> Properties udfProp = context.getUDFProperties(this.getClass());
> udfProp.setProperty("horton.json.udf.schema", schemaString);
> ...
> schema = Utils.getSchemaFromString(strSchema);
