Hbase+HDFS单机版配置

环境：ubuntu 13.04 ，hadoop-1.2.1+hbase-0.94.11

ubuntu 的/etc/hosts的文档修改如下，避免某些域名被映射成，127.0.1.1。

127.0.0.1       localhost
127.0.0.1       shallon-ThinkPad-X230
127.0.0.1       ubuntu.ubuntu-domain ubuntu

1、hadoop的配置

hadoop@shallon-ThinkPad-X230:~/hadoop-1.2.1/conf$ more core-site.xml
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>

<!-- Put site-specific property overrides in this file. -->
<configuration>
     <property>
         <name>fs.default.name</name>
         <value> hdfs://shallon-ThinkPad-X230:9000/hbase</value>
     </property>
<property> 
   <name>hadoop.tmp.dir</name> 
   <value>/home/hadoop/hadoop-${user.name}</value> 
   <description>A base for other temporary directories.</description> 
</property>
</configuration>

hadoop@shallon-ThinkPad-X230:~/hadoop-1.2.1/conf$ more masters
shallon-ThinkPad-X230
hadoop@shallon-ThinkPad-X230:~/hadoop-1.2.1/conf$ more slaves
shallon-ThinkPad-X230

hadoop@shallon-ThinkPad-X230:~/hadoop-1.2.1/conf$ more hdfs-site.xml
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>

<!-- Put site-specific property overrides in this file. -->
<configuration>
     <property>
         <name>dfs.replication</name>
         <value>1</value>
     </property>
</configuration>

启动hadoop的文件HDFS：

hadoop@shallon-ThinkPad-X230:~/hadoop-1.2.1/bin$ ./start-dfs.sh

hadoop@shallon-ThinkPad-X230:~/hadoop-1.2.1/bin$ jps
1493 NameNode
1780 DataNode
2226 SecondaryNameNode

尝试访问dfs。

hadoop@shallon-ThinkPad-X230:~/hadoop-1.2.1$ bin/hadoop dfs -ls /
Found 3 items
drwxr-xr-x   - hadoop supergroup          0 2013-09-22 22:05 /hbase
drwxr-xr-x   - hadoop supergroup          0 2013-09-22 15:54 /home
drwxr-xr-x   - hadoop supergroup          0 2013-08-30 15:18 /user

2、Hbase 配置

hadoop@shallon-ThinkPad-X230:~/hbase-0.94.11/conf$ vi hbase-site.xml

<configuration>
<property>
    <name>hbase.rootdir</name>
    <value> hdfs://shallon-ThinkPad-X230:9000/hbase</value>
  </property>
<property>
    <name>hbase.cluster.distributed</name>
    <value>true</value>
  </property>
</configuration>

黑体部分与上面配置的HDFS根路径匹配。指向本地配置的HDFS

hadoop@shallon-ThinkPad-X230:~/hbase-0.94.11/bin$ ./start-hbase.sh
hadoop@localhost's password:
localhost: starting zookeeper, logging to /home/hadoop/hbase-0.94.11/bin/../logs/hbase-hadoop-zookeeper-shallon-ThinkPad-X230.out
starting master, logging to /home/hadoop/hbase-0.94.11/bin/../logs/hbase-hadoop-master-shallon-ThinkPad-X230.out
hadoop@shallon-thinkpad-x230's password:
shallon-ThinkPad-X230: starting regionserver, logging to /home/hadoop/hbase-0.94.11/bin/../logs/hbase-hadoop-regionserver-shallon-ThinkPad-X230.out

查看HBase的启动进程
