HBase集群配置安装

hadoop-0.20.2

hbase-0.20.3

zookeeper-3.3.0

1:

tar zxvf hbase-0.20.3.tar.gz

2:

修改 ./hbase-0.20.3/conf/hbase-env.sh

export JAVA_HOME=/usr/local/java/

3:

创建文件./hbase-0.20.3/conf/hbase-site.xml

用户存放用户自定义的一些配置信息,相关配置项可以从 ./hbase-0.20.3/conf/hbase-default.xml中找到.

一个简单的hbase-site.xml如下:

<?xml version="1.0"?>

<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>

<configuration>

<property>

<name>hbase.rootdir</name>

<value>hdfs://master:9900/hbase</value>

</property>

<property>

<name>hbase.master.port</name>

<value>60000</value>

</property>

<property>

<name>hbase.cluster.distributed</name>

<value>true</value>

</property>

<property>

<name>dfs.replication</name>

<value>3</value>

</property>

</configuration>

注意：

把./hbase-0.20.3/conf/hbase-site.xml中

<name>hbase.rootdir</name>

<value>hdfs://master:9900/hbase</value>

和

./hadoop-0.20.2/conf/core-site.xml中

<name>fs.default.name</name>

<value>hdfs://master:9900/</value>

保持一致就可以了。

如果不一致的话,会报如下错误：

[hadoopuser
@master hbase-0.20.3]$ bin/hbase shell

HBase Shell; enter 'help<RETURN>' for list of supported commands.

Version: 0.20.3, rUnknown, Fri Apr 9 11:15:50 CST 2010

hbase(main):001:0>create 'test','fs'

NativeException: org.apache.hadoop.hbase.MasterNotRunningException: null

4:

创建文件./hbase-0.20.3/conf/regionservers

内容如下:

server01

server02

server03

server04

server05

5:

分发hbase-0.20.3到各台服务器(可能要根据实际情况更改JAVA_HOME)

6:

启动hbase

在master节点上启动：

bin/start-hbase.sh

localhost: starting zookeeper, logging to ********

starting master, logging to *********

server01: starting regionserver, logging to **********

server02: starting regionserver, logging to **********

server03: starting regionserver, logging to **********

server04: starting regionserver, logging to **********

server05: starting regionserver, logging to **********

7:

使用hbase shell

bin/hbase shell

hbase(main):012:0> create 'test','fs'

0 row(s) in 2.4360 seconds

hbase(main):013:0> list

test

1 row(s) in 0.0060 seconds

hbase(main):014:0> disable 'test'

0 row(s) in 2.0460 seconds

hbase(main):015:0> drop 'test'

0 row(s) in 0.0050 seconds

0 row(s) in 0.0050 seconds

0 row(s) in 0.0570 seconds

通过web方式可以查看运行在HBase下的zookeeper ：
