Elasticsearch路由分配的可能性和分片分配

Question

我有一個elasticsearch集羣，包含跨3個區域（A，B,C）分裂的10個節點。

的ES的配置文件包含：

cluster.routing.allocation.awareness.force.zone.values = "A,B,C"; 

我有一個包含=~ 283674文檔尺寸爲=~ 231MB單個索引（index1）。 這個指標的設置包括：

"number_of_replicas" : "2", "number_of_shards" : "5", 

碎片似乎整個區域，但它們不是均勻分佈的單一區域中正確分配（見下表，如C區| S =碎片，（P =小學| S =中學）

我能做些什麼，以正確分配我的碎片

Answer 1

我通過強迫每個主機碎片的數量和改變初級/每指數二次數量固定的問題：？

index.number_of_shards = "5"; 
index.number_of_replicas = "3"; 
index.routing.allocation.total_shards_per_node = "2"; 

這會導致每個節點均勻分佈2個分片。
