Hbase0.98.4/Hadoop2.4.1整合小結【原創】

　　設定hbase的數據目錄，修改conf/hbase-site.xml

<configuration>    
    <property>
        <name>hbase.cluster.distributed</name>
        <value>true</value>
        <description>The mode the clusterwill be in. Possible values are
            false: standalone and pseudo-distributedsetups with managed Zookeeper
            true: fully-distributed with unmanagedZookeeper Quorum (see hbase-env.sh)
        </description>
    </property>
    <property>
        <name>hbase.rootdir</name>
        <value>hdfs://Master:9000/hbase</value>
        <description>The directory shared byRegionServers.
        </description>
    </property>
    <property>
        <name>hbase.zookeeper.property.clientPort</name>
        <value>2222</value>
        <description>Property fromZooKeeper's config zoo.cfg.
        The port at which the clients willconnect.
        </description>
    </property>
    <property>
        <name>hbase.zookeeper.quorum</name>
        <value>Master</value><!--有多臺就填多臺主機名-->
        <description>Comma separated listof servers in the ZooKeeper Quorum.
        For example,"host1.mydomain.com,host2.mydomain.com,host3.mydomain.com".
        By default this is set to localhost forlocal and pseudo-distributed modes
        of operation. For a fully-distributedsetup, this should be set to a full
        list of ZooKeeper quorum servers. IfHBASE_MANAGES_ZK is set in hbase-env.sh
        this is the list of servers which we willstart/stop ZooKeeper on.
        </description>
    </property>
    <property>
        <name>hbase.zookeeper.property.dataDir</name>
        <value>/usr/local/hbase/zookeeper</value>
        <description>Property fromZooKeeper's config zoo.cfg.
        The directory where the snapshot isstored.
        </description>
    </property>
</configuration>

　　修改conf/regionservers，和hadoop的slaves同樣的操做，我仍是要把localhost幹掉的。同樣的，要配多個就放多個。

Master

　　替換hbase安裝目錄下的lib中使用的hadoop的jar包，改爲一致的。

　　原先hadoop相關的包爲

　　在hbase中lib目錄下創建一個sh(免得直接用命令把雜七雜八的所有複製過來了)，而後跑一下，把必須的那些jar包從hadoop安裝目錄導過來。

find -name "hadoop*jar" | sed 's/2.2.0/2.4.1/g' | sed 's/.\///g' > f.log
rm ./hadoop*jar
cat ./f.log | while read Line
do
find /usr/local/hadoop/share/hadoop -name "$Line" | xargs -i cp {} ./
done

rm ./f.log

　　lib包下面有個slf4j-log4j12-XXX.jar，在機器有裝hadoop時，因爲classpath中會有hadoop中的這個jar包，會有衝突，直接刪除掉，沒有就不用刪除了。在HBase的shell運行時，就能看到信息了，固然，查日誌也行。

　　完了直接啓動hbase，hadoop的dfs那邊會有反應了：

　　剩下的隨便折騰了。
