我正在尝试将我们的弹性搜索群集从1.6升级到2.3.4。升级似乎有效，我可以看到分片开始在Kopf中发生 - 但在某些时候，分片分配似乎停止，许多分片未分配，并且日志中没有报告错误。通常我会留下1200/3800个未分配的分片。
我们有一个典型的3节点集群，我正在我的本地计算机上试用这个独立节点，所有3个节点都在我的本地计算机上运行。
我看到过类似的症状报告 - 请参阅https://t37.net/how-to-fix-your-elasticsearch-cluster-stuck-in-initializing-shards-mode.html 。这里的解决方案似乎是手动分配我已尝试（并且有效）的分片，但我不知道在这里解释弹性搜索的行为。我不想沿着这条路走下去，因为我希望我的集群在没有干预的情况下自动旋转。
还有https://github.com/elastic/elasticsearch/pull/14494似乎是用最新的ES版本解决的，所以不应该成为一个问题。
日志文件中没有错误 - 我已经将根级别记录到＆＃39; DEBUG＆＃39;为了看到我能做什么。对于每个未分配的分片，我可以看到如下所示的行（来自主节点日志）：
[2016-07-26 09:18:04,859][DEBUG][gateway ] [germany] [index][4] found 0 allocations of [index][4], node[null], [P], v[0], s[UNASSIGNED], unassigned_info[[reason=CLUSTER_RECOVERED], at[2016-07-26T08:05:04.447Z]], highest version: [-1]
[2016-07-26 09:18:04,859][DEBUG][gateway ] [germany] [index][4]: not allocating, number_of_allocated_shards_found [0]
配置文件（删除了评论）：
cluster.name: elasticsearch-jm-2.3.4
node.name: germany
script.inline: true
script.indexed: true
如果我在重新分配停止后查询群集运行状况 - 我得到以下响应：
http://localhost:9200/_cluster/health?pretty

进一步查询分片 - 使用未分配的分片过滤到一个索引。可以看出 - shard 0和4未分配，而shard 1 2和3已分配：

手动重新路由未分配的分片似乎有效 - （去掉结果集）
