elasticsearch cluster health

is: int (primary + 3 replicas)/2) + 1 = 3 However, if you only have two nodes, you cannot index or delete any documents because the number of active parts is not enough. Note: The new index has one copy part by default, which means ** requires ** two active parts to meet the quorum requirements. Of course, this default setting will prevent us from performing operations in a single node cluster. To avoid this problem, the specified quantity takes effe

elasticsearch Cluster Server configurationFirst, installationElasticsearch is based on lence, and Lence is an open source library written in Java that relies on the Java runtime environment. The Elasticsearch version currently in use is 1.6, which requires jdk1.7 or more versions.This article uses the Linux system, the installation of a good Java environment, the

automatically built into a cluster named elasticsearch. 3. Plug-in Installation After the cluster is successfully installed, you need to check the index data and running status of the Cluster. You need to install some plug-ins for the index. To do a good job, you must first sharpen the tool. The following describes so

Rest interface Now that we have a functioning node (and cluster), the next step is to understand how to communicate with it. Fortunately, Elasticsearch provides a very comprehensive and powerful rest API that allows you to interact with your cluster using this REST API. Here are a few things you can do with this API: 1, check your

ElasticSearch cluster creation instance I started to research and search, and set up a simple ElasticSearch search cluster on my own virtual machine. I hope it will be helpful. Operating System Environment: Red Hat 4.8.2-16 Elasticsearch:

ES can automatically organize nodes of the same cluster name into the cluster by setting "node name" and "Cluster Name", and make many technologies transparent to users. If the user wants to manage the status of the view cluster, it can be done through some rest APIs. Other ES document translation reference:

The node then returns the response directly to the client. All of this is managed by Elasticsearch itself.2. Cluster health statusCurl Http
