elasticsearch降级挑战：分配给本地恢复的分片（后api）应该存在，但不存在

Question

在通过brew uninstall elasticsearch elasticsearch卸载Elasticsearch 0.9.x之后，我通过brew install elasticsearch-0.20 elasticsearch brew install elasticsearch-0.20安装了Elasticsearch 0.20.6。

当我通过启动服务器时

elasticsearch -f -D es.config=/usr/local/opt/elasticsearch-0.20/config/elasticsearch.yml

服务器无休止地记录以下异常：

[2014-09-04 18:06:14,613][WARN ][cluster.action.shard     ] [Jann] sending failed shard for [sensei_cucumber_news_feeds][0], node[gne6S-UYQPWnR9FqtKg_mw], [P], s[INITIALIZING], reason [Failed to start shard, message [IndexShardGatewayRecoveryException[[sensei_cucumber_news_feeds][0] shard allocated for local recovery (post api), should exists, but doesn't]]]

    at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:918)
    at java.lang.Thread.run(Thread.java:695)

我也想知道为什么索引仍然存在。 卸载后应该删除索引，对吗？

localhost:9200/_cluster/health?pretty=true显示红色信号：

{
  "cluster_name": "elasticsearch_gawlim",
  "status": "red",
  "timed_out": false,
  "number_of_nodes": 1,
  "number_of_data_nodes": 1,
  "active_primary_shards": 0,
  "active_shards": 0,
  "relocating_shards": 0,
  "initializing_shards": 4,
  "unassigned_shards": 867
}

当我尝试在服务器上执行搜索请求时，我得到了

SearchPhaseExecutionException Failed to execute phase [query], total failure; shardFailures: No active shards

删除索引查询有效。

我通过以下命令手动删除了索引，现在它可以工作了：

curl -XDELETE 'http://localhost:9200/index_name'
