MapperParsingException在Django的草垛與elasticsearch

我使用java 1.7.0_95，Django 1.8.4，Python 3.4.0，Django Rest Framework 3.1.3，ElasticSearch 2.3.1，pyelasticsearch 1.4和Django Haystack 2.4.1MapperParsingException在Django的草垛與elasticsearch

每次我嘗試做python manage.py rebuild_index時間我經歷elasticsearch錯誤做rebuild_index。這是錯誤：

 
MapperParsingException[Root mapping definition has unsupported parameters: [_boost : {null_value=1.0, name=boost}]] 
     at org.elasticsearch.index.mapper.DocumentMapperParser.checkNoRemainingFields(DocumentMapperParser.java:171)

這裏是我的配置：

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

HAYSTACK_SIGNAL_PROCESSOR = 'haystack.signals.RealtimeSignalProcessor' 

HAYSTACK_SEARCH_RESULTS_PER_PAGE = 40

沒有'ElasticSearch 1.9.0'。 –

感謝您指出@AndreiStefan，我在我的問題中將其修正爲2.3.1。必須把它和其他東西混合起來。 –

有一個相關的django-haystack問題刪除boost參數，因此不再在ElasticSearch> = 2的支持：

Remove boost which is now unsupported

在更改之前，django-haystack在ElasticSearch後端的映射中使用_boost參數。對主分支進行了更改。你可以在這個時刻做的事情：

直接從github上安裝的django-haystack開發版：

pip install -e git+https://github.com/toastdriven/[email protected]#egg=django-haystack

降級ElasticSearch在升級到2日前最新的穩定版本，我認爲這爲1.7.3

而且，這裏是相關討論：

Django haystack LocationField created as string instead of geo_point in elasticsearch
