Indexing AVRO Documents

Hi

I have a code to read AVRO that iterates over records and builds the XContentBuilder
object from it and indexes it.
I have introduced a code for Auto-Classification that accepts the record as
XContentBuilder.string() and retruns a String with Catagories in it.

XContentBuilder jBuilder = jsonBuilder().startObject();

jBuilder.field("data",input);
String s=a.addCategory(jBuilder.string());
jBuilder.field("tags", s);// line 3
Now I am trying to add the catagories to XContentBuilder object (line 3)
before indexing it but have the following exception thrown:

org.elasticsearch.common.jackson.core.JsonGenerationException: Can not
write a field name, expecting a value
how do i resolve this issue?

Thanks

Kuwar Sahani

Can you post all your code?
I mean that I don't see any endObject() method call.
What is the content of s? Could it be null?

hi
unable to attach a file somehow.
writing a demo code.

public class AutoClassification {

public String addCategory(String input) {

String next;

while((next=inputReader.readLine())!=null){
if(input.contains(next)){
categories.add("""+next+""");
}

}
}
catch (Exception e) {

}

return categories.toString();
}
public static void main(String[] args) throws IOException {
AutoClassification a= new AutoClassification();
XContentBuilder jBuilder = jsonBuilder().startObject();
String input="XYZ is an IT company.it has launched the product in BIG
DATA Space";
jBuilder.field("data",input);
String s=a.addCategory(jBuilder.bytesStream().toString());
System.out.println(s);
//s =["IT","XYZ"]
//the error is thrown here:
jBuilder.field("tags", s);
jBuilder.endObject();
System.out.println(jBuilder.string());
}
}

Use GIST to post your code.

If you need to add an array to your json (using jsonbuilder), use startArray() and endArray() instead of try to build a String like "["IT","XYZ"]" and put that in a tag.

once you call the .string() method of an XContentBuilder object, it does
not allow to add another field to it, leave aside the data type to be added.
