reindex method in class Elasticsearch timeout

When I’m using this method with body=‘{“source”:{“index”: …}, “dest”:{“index”: …}}’, the same with REST api, I get a timeout error from urllib3 as follows:

File "/usr/lib/python2.7/site-packages/elasticsearch/client/utils.py", line 69, in _wrapped
    return func(*args, params=params, **kwargs)
File "/usr/lib/python2.7/site-packages/elasticsearch/client/__init__.py", line 1278, in reindex
    params=params, body=body)
  File "/usr/lib/python2.7/site-packages/elasticsearch/transport.py", line 327, in perform_request
    status, headers, data = connection.perform_request(method, url, params, body, ignore=ignore, timeout=timeout)
  File "/usr/lib/python2.7/site-packages/elasticsearch/connection/http_urllib3.py", line 102, in perform_request
    raise ConnectionTimeout('TIMEOUT', str(e), e)
ConnectionTimeout: ConnectionTimeout caused by - ReadTimeoutError(HTTPConnectionPool(host=..., port=...): Read timed out. (read timeout=10))

However the reindex request did get passed to elasticsearch host and processed. It seems that the arguments of this method don’t work as it’s documented in either readthedocs or method description.

This error means that you didn’t get a response from elasticsearch in the allotted time (10 seconds by default). Which makes sense since the reindexing is a big operation.

To avoid this you need to set your timeout higher - either for the whole client (by passing timeout=N when creating the client) or for this individual request using the request_timeout=N parameter to the reindex call.

Hope this helps
