Set Request Timeout in Elastic Search for bulk loads

I wanted to set the request time to 20 sec or more in Elasticsearch Bulk uploads. Default time is set to 10 sec and my Warning message days it takes 10.006 sec. And, right after displaying the waring the execution is throwing an error

Now, I wanted to set the Request Timeout either for every request taking input from user or any value set by default.

Error Message:

    WARNING:elasticsearch:HEAD /opportunityci/predictionsci [status:404 request:0.080s]

Use parameter 'request_timeout'

E.g.:

bulk(es, records, chunk_size=500, request_timeout=20)
