Django haystack with elasticsearch, indexing issue

Question

Im using django-haystack with elasticsearch but there is a problem with indexing. When rebuilding my index

 python manage.py rebuild_index 

following error is raised:

Traceback (most recent call last):

Timeout: HTTPConnectionPool(host='127.0.0.1', port=9200): Request timed out. (timeout=10)

I used django-haystack - 2.0.0-beta, pyelasticsearch - 0.5, elasticsearch 0.20.6, java version "1.6.0_24"

Haystack Settings

    HAYSTACK_CONNECTIONS = {
        'default': {
            'ENGINE': 'haystack.backends.elasticsearch_backend.ElasticsearchSearchEngine',
            'URL': 'http://127.0.0.1:9200/',
            'INDEX_NAME': 'haystack',
        },
    }

And Im sure my elasticsearch serivce is running.

It sounds like your ElasticSearch instance is unavailable. What's the result of "curl -XGET 'localhost:9200'"? You should see JSON output with the server status and version. – Anton

Answer 1

This does not necessarily mean that your es server is down, especially if you get something reasonable returned with curl -I "127.0.0.1:9200". More likely, this is an issue of your request simply not getting enough time given the speed of connections involved.

Interestingly, the default timeout set in pyelasticsearch is 60 seconds, see def __init__(self, urls, timeout=60, max_retries=0, revival_delay=300): in https://github.com/rhec/pyelasticsearch/blob/master/pyelasticsearch/client.py. However, haystack overwrites that with its default setting, which is 10 seconds, as per self.timeout = connection_options.get('TIMEOUT', 10) in https://github.com/toastdriven/django-haystack/blob/master/haystack/backends/__init__.py.

As you can see though, haystack allows you to easily modify your setting, by adding 'TIMEOUT': 60, to your engine configuration.

And solved :)

Answer 2

I too had the similar problem

sudo service elasticsearch restart

then it worked

This solved my problem after my server had run out of disk space. – Treachery

Answer 3

are you running

bin/elasticsearch -f 

I think you are not running the searchengine.
