hadoop2.6.0+zookeeper+hbase1.0.0環境搭建

1.  環境準備

   zookeeper集羣

   hadoop集羣，hadoop的搭建參考  http://my.oschina.net/u/2311010/blog/508139

2. 集羣組成

hostname	hadoop cluster	ip	hbase cluster
master	namenode  & zookeeper	192.168.137.117	master
slave1	datanode	192.168.137.117
slave2	datanode    & zookeeper	192.168.137.118	regionserver
slave3	datanode    & zookeeper	192.168.137.119	regionserver

  3.   下載hbase-1.0.0包，http://archive.apache.org/dist/hbase/

  4.    解壓，配置環境變量

cd /data0
tar zxvf hbase-1.0.0-bin.tar.gz

vi ~/.bashrc
export HBASE_HOME=/data0/hbase-1.0.0
export PATH=$HBASE_HOME/bin:$PATH
source ~/.bashrc

  5.    hbase集羣配置

vi hbase-env.sh
export JAVA_HOME=/usr/java/jdk1.7.0_71
export HBASE_MANAGES_ZK=false #使用獨立的zookeeper集羣


vi hbase-site.xml 
<configuration>
    <property>
        <name>hbase.rootdir</name>
        <!--這裏的9000端口和hadoop中的core-site.xml中的hdfs端口相同-->
        <value>hdfs://master:9000/hbase</value>
    </property>
    <property>
        <name>hbase.cluster.distributed</name>
        <value>true</value>
    </property>
    <property>
        <name>hbase.master</name>
        <value>master:60000</value>
    </property>
    <property>
        <name>hbase.zookeeper.quorum</name>
        <value>master,slave2,slave3</value>
    </property>
    <property>
        <name>hbase.zookeeper.property.clientPort</name>
        <value>2181</value>
        <description>Property from ZooKeeper's config zoo.cfg. The port at which the clients will connect.</description>
    </property>
</configuration>

vi regionservers
slave2
slave3

  6.    將配置好的文件scp到slave2,slave3節點的$HBASE_HOME/conf下

  7.    在master節點啓動hbase

cd $HBASE_HOME/bin
./start-hbase.sh

遇到的問題，因爲集羣機器的時間不統一，致使regionserver啓動失敗。

解決辦法是手工修改系統的硬件時間

date -s 時間
clock -w
