Python 与Heroku和Django一起使用盆景Elasticsearch的IndexMissingException

环境：我正在使用Python 2.7.2运行Django==1.5.4，并部署到Heroku。我正在使用带有弹性搜索的Haystack。在Heroku上，我正在使用盆景弹性搜索插件

问题：运行rebuild_index命令时，在销毁索引时遇到“读取超时错误”，在尝试创建索引时遇到“IndexMissingException”。日志输出如下所示：

> heroku run python manage.py rebuild_index
Running `python manage.py rebuild_index` attached to terminal... up, run.1762

WARNING: This will irreparably remove EVERYTHING from your search index in connection 'default'.
Your choices after this are to restore from backups or rebuild via the `rebuild_index` command.

Removing all documents from your index because you said so.
Failed to clear Elasticsearch index: Non-OK response returned (404): u'IndexMissingException[[msdc] missing]'

验证：我已经明确创建了索引，我通过尝试重新创建并运行以下测试步骤对其进行了验证：

> curl -X POST http://index@box.us-east-1.bonsai.io/msdc
{"error":"Index already exists.","status":400}%

> curl -X POST http://index@boc.us-east-1.bonsai.io/msdc/test -d '{"title":"hello, world"}'
{"ok":true,"_index":"msdc","_type":"test","_id":"9q8t4m0sTgy6JeGkueL54Q","_version":1}%   

> curl -X POST http://index@box.us-east-1.bonsai.io/msdc/_search -d '{}'                  
{"took":2,"timed_out":false,"_shards":{"total":1,"successful":1,"failed":0},"hits":{"total":1,"max_score":1.0,"hits":[{"_index":"msdc","_type":"test","_id":"9q8t4m0sTgy6JeGkueL54Q","_score":1.0, "_source" : {"title":"hello, world"}}]}}% 

我对Elasticsearch和Heroku相当陌生，所以我可能错过了一个关键步骤。如果您能帮助排除此错误，我们将不胜感激
