Lucene 弹性搜索索引硬缺失异常

每当启动节点时，我都会收到此错误。 怎么了

[2012-10-12 10:00:38,196][DEBUG][action.admin.indices.status] [Gorgilla] [monitoring][1], node[dbnnA1NOQ1ubysyADvazFg], [P], s[INITIALIZING]:

我的ES版本->0.19.0

设置：

ES_HOME/bin/service/elasticsearch.conf file:
 set.default.ES_HEAP_SIZE=1024
 set.default.ES_MIN_MEM=1048576
 set.default.ES_MAX_MEM=1048576

elasticsearch.yml
 index.cache.field.type: soft
 index.cache.field.max_size: 1000
 bootstrap.mlockall: true

index settings:
"number_of_shards":5
"number_of_replicas":1

---

有什么帮助吗？
