hadoop--搭建hbase叢集
阿新 • • 發佈:2019-01-27
背景
我們已經搭建了HA高可用的hdfs叢集,現在要在hdfs叢集的基礎上搭建hbase叢集。可以看我之前的一篇hdfs叢集搭建,
自行官網下載hbase,我這裡選用1.2.3版本
修改hbase配置檔案
1. hbase-env.sh//#配置一下JAVA環境
export JAVA_HOME=/usr/local/jdk
//# Tell HBase whether it should manage it's own instance of Zookeeper or not.
export HBASE_MANAGES_ZK=false
2. hbase-site.xml
3. 配置regionservers,regionserver的節點<?xml version="1.0"?> <?xml-stylesheet type="text/xsl" href="configuration.xsl"?> <!-- /** * * Licensed to the Apache Software Foundation (ASF) under one * or more contributor license agreements.

es02
es03
es04
注意事項
由於hdfs配置了HA高可用,我們在hadoop的hdfs-site.xml中配置了"dfs.nameservices"的名稱“mycluster”他下面有兩個名稱節點“nn1,nn2”,我們需要把hadoop中的hdfs-site.xml和core-site.xml放到hbase目錄下的conf資料夾中,不然hbase叢集在啟動的時候會報"unkonwHostException"。
啟動測試
//啟動命令
start-hbase.sh
