flinkx同步es2hive

一.elasticsearch环境准备

1. elasticsearch 6.4.3
2. es-head

elasticsearch的部署基于docker进行部署

首先我们来看一下目录结构

代码语言：javascript复制

cd docker
mkdir -p es
cd es
mkdir -p conf
mkdir -p data
mkdir -p logs

下面看一下docker-compose.yml

代码语言：javascript复制

version: '3'
services:
  elasticsearch:
    image:  elasticsearch:6.4.3
    container_name: elasticsearch
    volumes:
      - $PWD/data:/usr/share/elasticsearch/data
      - $PWD/logs:/user/share/elasticsearch/logs
    ports:
        - '9200:9200'
        - '9300:9300'
    environment:
        - discovery.type=single-node
        - http.port=9200
        - http.cors.enabled=true
        - http.cors.allow-origin=*
        - http.cors.allow-headers=X-Requested-With,X-Auth-Token,Content-Type,Content-Length,Authorization
        - http.cors.allow-credentials=false
        - bootstrap.memory_lock=true
        - 'ES_JAVA_OPTS=-Xms512m -Xmx512m'
  es-head:
    image: tobias74/elasticsearch-head:6
    container_name: es-head
    ports:
      - '9100:9100'
    links:
      - elasticsearch
