该类继承TransportMasterNodeAction,它会启动一个异步线程来执行任务,如果当前节点是master节点,则执行masterOperation,否则转发给master节点(每个节点在启动时会加入集群,同时保存完整的集群信息,该信息又Discovery模块维护) TransportCreateIndexAction将CreateIndexRequest转换为CreateIndexClusterStateUpdateRequest,将请求作为参数...
2、在es的config的elasticsearch.yml中加入: cluster.routing.allocation.disk.watermark.flood_stage: 99% # 设置空间阈值99% cluster.routing.allocation.disk.threshold_enabled: false # 设置不关心磁盘空间,就算满了 3、设置索引read_only_allow_delete值为false 4、重启es 索引状态位只读: 1、设置索引read_only...
1)Near Realtime(NRT):近实时,从写入数据到数据可以被搜索,整个过程所需要的时间非常短(大概 1 秒),并且基于 ES 执行搜索和分析同样可以达到秒级。 2)Cluster:集群,包含多个节点,当然也可以只包含一个节点。 3)Node:集群中的一个节点,每个节点都有一个名称(默认随机分配),节点的名称还是比较重要的,尤其是在...

cluster:ES的集群标识为集群名称;默认为"elasticsearch"。节点就是靠此名字来决定加入到哪个集群中。一个节点只能属于于一个集群。 Node:运行了单个ES实例的主机即为节点。用于存储数据、参与集群索引及搜索操作。节点的标识靠节点名。 Shard:将索引切割成为的物理存储组件;但每一个shard都是一个独立且完整的索引;创建...
Reconcile ElasticSearch Cluster Business Config & Resource Reconcile Node Spec 首先是清理不匹配的 Kubernetes 资源,然后检查并创建 Script ConfigMap,以及两个 Service。 ElasticSearch 会用到两个 Service,便是在这一步进行创建和矫正的: - TransportService:headless Service,es 集群 zen discovery 使用 - ExternalSe...
If you find that the configurations of your cluster do not meet your expectations after the cluster is created, you can refer to the methods provided in the following table to modify the configurations. Warning If you need to unsubscribe from or release your cluster, first back up your dat...

Easily reproducable on 3 nodes cluster. It almost always fails to allocate last shard when using these index settings: PUT test_index { "settings": { "number_of_shards": 3, "number_of_replicas": 1, "routing": { "allocation": { ...
