Django haystack与elasticsearch,索引问题

Question

我使用带有弹性搜索的django-haystack,但索引存在问题.重建我的索引时

 python manage.py rebuild_index 

引发以下错误:

Traceback (most recent call last):
  File "/home/palo/.virtualenvs/toro/local/lib/python2.7/site-packages/haystack/management/commands/update_index.py", line 210, in handle_label

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

我使用了django-haystack - 2.0.0-beta,pyelasticsearch - 0.5,elasticsearch 0.20.6,java version"1.6.0_24"

干草堆设置

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

我确定我的弹性搜索服务正在运行.

这并不一定意味着你的es服务器已关闭,特别是如果你得到了合理的返回curl -I "127.0.0.1:9200".更可能的是,考虑到所涉及的连接速度,这是您的请求的问题,根本没有足够的时间.

有趣的是,在pyelasticsearch设置默认的超时时间为60秒,看def __init__(self, urls, timeout=60, max_retries=0, revival_delay=300):在https://github.com/rhec/pyelasticsearch/blob/master/pyelasticsearch/client.py.然而,干草堆将覆盖使用其默认设置,即10秒,按照self.timeout = connection_options.get('TIMEOUT', 10)在https://github.com/toastdriven/django-haystack/blob/master/haystack/backends/__init__.py.

如您所见,haystack允许您通过添加'TIMEOUT': 60,引擎配置轻松修改设置.

并解决了:)
