Hbase安装 - 伪分布式模式

网站:

http://hbase.apache.org/

版本对应关系:

通过lib目录下的hadoop-core- ...jar可以看出适配的hadoop版本

hbase-0.98.6-hadoop2    => hadoop 2.2
hbase-0.96.2-hadoop2    => hadoop 2.2
hbase-0.98.6-hadoop1    => hadoop 1.2.1
hbase-0.96.2-hadoop1    => hadoop 1.2.1

Hbase安装 : 伪分布模式

在单点模式的基础上继续编辑hbase-env.sh 增加HBASE_CLASSPATH环境变量编辑hbase-site.xml打开分布模式覆盖hadoop核心jar包启动hbase验证启动

编辑配置

hbase-env.sh

#用于帮助hbase找到hadoop
export HBASE_CLASSPATH=/home/hadoop/hadoop-1.2.1/conf

hbase-site.xml

<property>
<name>hbase.rootdir</name>
<value>file://home/hadoop/hbase/data</value>
</property>
<property>
<name>hbase.cluster.distributed</name>
<value>true</value>
</property>

覆盖hadoop核心jar包这是关键一步, 主要目的是防止因为hbase和hadoop版本不同步出现兼容问题, 造成hmaster启动异常

启动hbase并验证

[hadoop@hadoop1 hbase]$ ./bin/start-hbase.sh

starting master, logging to /home/hadoop/hbase/bin/../logs/hbase-hadoop-master-hadoop1.out
