我有一个包含10个节点的弹性搜索群集，这些节点分为3个区域（A，B，C）。
ES配置文件包含：
cluster.routing.allocation.awareness.force.zone.values = "A,B,C";
我有一个索引（index1），其中包含=~ 283674个文档，大小为=~ 231MB。
此索引的设置包含：
"number_of_replicas" : "2", "number_of_shards" : "5",
碎片似乎在区域内正确分布，但在单个区域内它们分布不均匀（见下表，例如区域C | S =碎片，（P =初级| S =次级）
如何正确分发我的碎片？

答案 0 :(得分：1)
我通过强制每个主机的分片数量和更改每个索引的主要/辅助数量来修复此问题：
index.number_of_shards = "5";
index.number_of_replicas = "3";
index.routing.allocation.total_shards_per_node = "2";
这导致每个节点有2个分片在区域内均匀分布。
