当使用python更新文档时，Elasticsearch抛出异常`index_failed_engine_exception`

Question

我正在尝试借助python脚本更新我的Elasticsearch文档，但是在进行一些文档更新后，我得到了以下异常：

TransportError(500, u'index_failed_engine_exception', {u'status': 500, 
u'error': {u'index': u'catalog', u'root_cause': [{u'index': u'catalog', 
u'reason': u'Index failed for [variant#5a61e925ae8bdc45df6939fa]', 
u'type': u'index_failed_engine_exception', u'shard': u'3'}], 
u'caused_by': {u'reason': u'translog is already closed', u'type': 
u'already_closed_exception'}, u'shard': u'3', u'reason': u'Index failed 
for [variant#5a61e925ae8bdc45df6939fa]', u'type': 
u'index_failed_engine_exception'}})

请帮助我了解它为什么会发生？

这是我的python代码：

def updateElasticDoc(sku, facilityId, reason, comment, replaceVariant):
    if sku and  replaceVariant:
        docs = getElasticSearchDoc1(sku, facilityId)
        for doc in docs:
            docC = doc['_source']
            flag = es.update(doc_type='variant', index='catalog',id=docC['facility_variant_id'],
                body={"doc": {"replaced_variant": {"pack_type" : replaceVariant['pack_type'], 
                                                    "pack_size" : replaceVariant['pack_size'], 
                                                    "drug_strength" : replaceVariant['drug_strength'],
                                                    "variant_id" : str(replaceVariant['_id']),
                                                    "name" : replaceVariant['name'], 
                                                    "sku" : replaceVariant['sku']
                                                  },
                 "status": "Retired", "variant_status" : "Retired", "reason" : reason, "variant_reason" : reason, "comment" : comment,
                 "is_retired" : True, "retired": True}})
            if flag:
                print (flag)

在elasticsearch.yml中更改设置 index.translog.sync_interval ： 10s 。如果10倍无效，请增加尝试。

有关更多信息，请参考Translog settings。

您可以按照上述步骤为索引动态更新此设置：

1）关闭索引：

POST my_index/_close

2）更新设置：

PUT my_index/_settings
{
  "index.translog.sync_interval" : "10s"
}

3）再次打开索引：

POST my_index/_open
