HBase伪分布环境搭建过程记录

 

公司项目组需要在异地机房进行测试，买的是阿里云的机器，领导一句话花最少的钱办最大的事情，所以预算是一台机器，一core的cpu,4G内存，20G硬盘，想在这上面搭建一套高大上的HBase

 

，这就好比给你一包方便面想让你做出一桌满汉全席出来， 尼玛这不是为难我吗！！

 

 

好吧，吐槽完之后该搬砖还得搬砖，最开始想法是搭建最简单的standlone版本的HBase，只需要基于local file，结果按照guide折腾半天起不来，感觉这种方案非常不靠谱的样子，只好退而

 

求其次，搭建伪分布环境的HBase，好吧，下面是搭建过程。

 

1. 前戏-版本依赖

 

hbase和hadoop是两个专情又有强迫症的二货，对于兼容性要求很高，安装之前请自行关注版本是否匹配，我这次使用的是hbase-0.94.12和hadoop-0.20，如果版本不对后续会遇到各种莫名其

 

妙的坑爹错误

 

2. 过程-HBase配置文件修改

 

hbase-env.sh 需要改的地方

 

JAVA_HOME=/opt/taobao/java

export JAVA_HOME=${JAVA_HOME}

export HBASE_CLASSPATH=/home/admin/hadoop-0.20/conf/

export HBASE_MANAGES_ZK=true

  <value>hdfs://localhost:9000</value>

4. 注意事项

 

如果发现本机可以访问，但远程主机无法访问，检查一下/etc/hosts,可能需要绑定hosts
