i use kafka(input) and logstash (1.5.2) with (output) elasticsearch (ES 1.5.2 or 1.6.0)
- i change the code in plugin output elasticsearch to be able to update documents and for that i use the UpdateRequest API.
 https://github.com/logstash-plugins/logstash-output-elasticsearch/pull/188/files
- until Elasticsearch 1.5.0 the function request.script(args[:_script]) works without problem but after in versions 1.5.2 or 1.6.0 this function doesn't work anymore
Even a simple action in the script like update a integer field fail :
{"document_id":"2754","script":"ctx._source.country = 76","action":"update","retry_on_conflict":3}
error log :
    failedactionwithresponseof400,
