I used Elasticsearch-1.1.0 to index tweets. The indexing process is okay. Then I upgraded the version. Now I use Elasticsearch-1.3.2, and I get this message randomly:
Exception happened: Error raised when there was an exception while talking to ES.
ConnectionError(HTTPConnectionPool(host='127.0.0.1', port=8001): Read timed out. (read timeout=10)) caused by: ReadTimeoutError(HTTPConnectionPool(host='127.0.0.1', port=8001): Read timed out. (read timeout=10)).
Snapshot of the randomness:
Happened --33s-- Happened --27s-- Happened --22s-- Happened --10s-- Happened --39s-- Happened --25s-- Happened --36s-- Happened --38s-- Happened --19s-- Happened --09s-- Happened --33s-- Happened --16s-- Happened
--XXs-- = after XX seconds
Can someone point out on how to fix the Read timed out problem?
Thank you very much.
Its hard to give a direct answer since the error your seeing might be associated with the client you are using. However a solution might be one of the following:
1.Increase the default timeout Globally when you create the ES client by passing the timeout parameter. Example in Python
es = Elasticsearch(timeout=30)
2.Set the timeout per request made by the client. Taken from Elasticsearch Python docs below.
# only wait for 1 second, regardless of the client's default
es.cluster.health(wait_for_status='yellow', request_timeout=1)
The above will give the cluster some extra time to respond
