ES output fails with 400 due to types removal

[ycombinator]

• Version: master / 8.0.0
• Operating System: macOS X 10.14.6
• Config File (if you have sensitive info, please remove it): default one
• Sample Data:
• Steps to Reproduce:

1. Run Logstash with a simple pipeline sending data to Elasticsearch:

   ./bin/logstash --log-level=debug -e 'input { stdin {} } output { elasticsearch {} }'
   

2. Send a line of input:

   foobar
   

3. Observe that the logs show a 400 errors from the Elasticsearch output plugin:

   [2019-10-16T11:47:17,096][ERROR][logstash.outputs.elasticsearch][main] Encountered a retryable error. Will Retry with exponential backoff  {:code=>400, :url=>"http://127.0.0.1:9200/_bulk", :body=>"{\"error\":{\"root_cause\":[{\"type\":\"illegal_argument_exception\",\"reason\":\"Action/metadata line [1] contains an unknown parameter [_type]\"}],\"type\":\"illegal_argument_exception\",\"reason\":\"Action/metadata line [1] contains an unknown parameter [_type]\"},\"status\":400}"}
   

I believe this is happening because Elasticsearch recently removed the _type property from it's bulk request metadata JSON headers (and the bulk API URL as well).

@robbavey I believe this issue has now been resolved by #892 and can be closed?
