Unable to start Logstash: Encountered a retryable error. Will Retry with exponential backoff


#1

Hi,

Logstash version: 6.1.2
ES version: 6.1.2

I am using Logstash to transferring data to Elasticsearch.

After starting logstash it just keeps giving logs like below:
[2018-05-02T18:48:56,892][ERROR][logstash.outputs.elasticsearch] Encountered a retryable error. Will Retry with exponential backoff {:code=>400, :url=>"http://hostname:9200/_bulk"}
[2018-05-02T18:50:00,898][ERROR][logstash.outputs.elasticsearch] Encountered a retryable error. Will Retry with exponential backoff {:code=>400, :url=>"http://hostname:9200/_bulk"}

In addition, Elasticsearch is starting and has no error message about this.
I think it's a pure Logstash failure but still do not know how to solve it after searching for many similar problems.

Can you please give some advice on this? Thanks very much!
