MapperParsingException on doing rebuild_index in django-haystack with elasticsearch

I'm using 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 and Django Haystack 2.4.1

I'm experiencing an error in elasticsearch every time I try to do python manage.py rebuild_index. This is the error:

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

        at java.lang.Thread.run(Thread.java:745)

Here is my configuration:

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

There is a relevant django-haystack issue to remove the boost parameter which is no longer supported in ElasticSearch >= 2:

Before that change, django-haystack was using the _boost parameter in the mapping for the ElasticSearch backend. The change was made to the master branch. You can do things at this moment:

  • install the development version of django-haystack directly from github:

    pip install -e git+https://github.com/toastdriven/django-haystack.git@master#egg=django-haystack

  • downgrade ElasticSearch to the latest stable version before the upgrade to the 2nd, I think it is 1.7.3
