elasticsearch and machine learning

the two plug-in head and Bigdesk is for the cluster management, I in this example is only a single-machine installation, so there is no need to install the two plug-ins, there is a need to refer to the following links:http://blog.csdn.net/a806267365/article/details/51020633or more links can refer to learning communication:http://blog.csdn.net/sinat_28224453/article/details/51134978This article also refers

In the process of starting to access ES encountered a variety of wonderful problems.1. On-line various versions of the start-up mode is confusing to know how to start. Simple and rude--execute directly in the bin directory of ES./elasticsearch//display start, CTRL + C can stop, such as to operate, change the terminal./elasticsearch-d background boot, can continue operation at the current terminal//backgroun

Nodes in a multi-machine cluster can be divided into master nodes and data nodes, using the Zen Discovery (Zen discovery) mechanism in the configuration file to manage different nodes. Zen Discovery is the default discovery mechanism that comes with ES, using multicast to discover other nodes. As soon as you start a new ES node and set the same name as the cluster, the node is added to the cluster.Select 192.168.0.224 this

It provides a distributed multi-user-capable full-text search engine, based on a restful web interface.Recently work needed, and then studied the next es. By the way, the process of learning is recorded, it is also convenient for a long time to review again, or other environment to configure the reference.Tools/Materials

0x01 Memory Tuning There are several ways to adjust ES memory allocations, and it is recommended that you adjust the settings in/etc/sysconfig/elasticsearch (you can also modify the startup script under bin directly). # Directory where the elasticsearch binary distribution resides Es_home=/usr/share/elasticsearch # Heap Size (defaults to 256m min, 1g max) # Modi

Elasticsearch Learning Notes (iv) Mapping mapping Mapping Brief IntroductionElasticsearch is a schema-less system, but does not represent no shema, but rather guesses the type of field you want based on the underlying type of JSON source data. Mapping is similar to a data type in a static language in Elasticsearch, but the mapping has some other meaning than the

Overview Elasticsearch is a search server based on Lucene. The following abbreviation ES, the version is about 2.3. The ES version is more than 5.3, but many companies are not using the latest version, and so is my company. In the absence of contact with ES, I do not know the framework of this full-text indexing, plus my English is not good, when the study really brought me a lot of problems, trampled a lot of pits. Next, I will introduce the process

Elasticsearch provides developers with a set of restful interfaces based on the HTTP protocol, and only needs to construct a rest request and parse the JSON returned by the request for access to the Elasticsearch server. Elasticsearch API interface is rich in functionality, including clustering, monitoring, deployment management, etc., also contains commonly used

Recently, the development team trained Elasticsearch, ready to launch a new project, I also went to gather the excitement, the following to record the learning process.First, installation1, the environment needs jdk1.8;2.

A few concepts about Elasticsearch:1) in Elasticsearch, the document belongs to the type, and the type is indexed to index, which can be likened to the traditional relational database for ease of understanding:Columns, Tables, DataBases, relational DBElasticsearch, Indices, Types,In a elasticsearch cluster, you can include multiple index indices, each of which ca
