hbase0.9.6 分布式安装

hbase 完全分布式安装，目前是3台机子，分别为：
192.168.80.101 hadoop1 (作为hbase的master节点)
192.168.80.102 hadoop2   (作为hbase的regionserver节点)
192.168.80.103 hadoop3  (作为hbase的regionserver节点)

解压hbase-0.94.2-security.tar.gz与重命名
#cd /usr/local #tar -zxvf hbase-0.94.2-security.tar.gz #
mv hbase-0.94.2-security hbase
修改/etc/profile文件。
#vi /etc/profile
增加 export HBASE_HOME=/usr/local/hbase
修改 export PATH=$JAVA_HOME/bin:$HADOOP_HOME/bin:$HBASE_HOME/bin:$PATH
保存退出 #source /etc/profile
修改$HBASE_HOME/conf/hbase-env.sh文件
export JAVA_HOME=/usr/local/jdk
export HBASE_MANAGES_ZK=false 保存后退出
修改$HBASE_HOME/conf/hbase-site.xml
<configuration>
    <property>
  <name>hbase.rootdir</name>
  <value>hdfs://hadoop1:9000/hbase</value>
</property>
<property>
  <name>hbase.cluster.distributed</name>
  <value>true</value>
</property>
<property>
  <name>hbase.zookeeper.quorum</name>
  <value>hadoop1,hadoop2,hadoop3</value>
</property>
<property>
  <name>dfs.replication</name>
  <value>1</value>
</property>
</configuration>
修改 $HBASE_HOME/conf/regionservers  文件夹
Hadoop2
Hadoop3

  修改好后，通过如下命令复制到其他hadoop2，hadoop3三个节点。
  scp -r   hbase root@hadoop2/usr/local/
  scp  -r  hbase root@hadoop3/usr/local/

经过上面配置完后，可以通过bin/start-hbase.sh命令启动hbase集群。注意启动hbase前，先要启动hadoop和zookeeper集群。

启动成功后，可以通过http://hadoop1:60010查看hbase的管理页面。



错误表现：

SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/usr/hbase/lib/slf4j-log4j12-1.6.4.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/usr/hadoop/share/hadoop/common/lib/slf4j-log4j12-1.7.5.jar!/org/slf4j

发生jar包冲突了：
分别为：
file:/usr/hbase/lib/slf4j-log4j12-1.6.4.jar!/org/slf4j/impl/StaticLoggerBinder.class
file:/usr/hadoop/share/hadoop/common/lib/slf4j-log4j12-1.7.5.jar!/org/slf4j/impl/StaticLoggerBinder.class
移除其中一个jar包即可

hbase 安装完成后，创建表时报错
报错信息如下：

hbase(main):004:0> create 't1', {NAME => 'f1', VERSIONS => 5}
ERROR: Can't get master address from ZooKeeper; znode data == null
查看日志如下
org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.ipc.RpcServerException):
                          Unknown out of band call #-2147483647

解决方法：
hbase0.96.0中lib带的相关hadoop的jar包为hadoop-2.1.0-beta版，所以要做以下修改：
          <1>把所有节点的hbase-0.96.0中lib包中所有以hadoop开头的jar包全部删除                       
    rm -rf hadoop-*.jar
          <2>将hadoop-2.2.0相关的jar包拷贝至hbase的lib下，具体jar包有：
hadoop-annotations-2.2.0.jar
hadoop-auth-2.2.0.jar
hadoop-common-2.2.0.jar
hadoop-hdfs-2.2.0.jar
hadoop-hdfs-2.2.0-tests.jar
hadoop-mapreduce-client-app-2.2.0.jar
hadoop-mapreduce-client-common-2.2.0.jar
hadoop-mapreduce-client-core-2.2.0.jar
hadoop-mapreduce-client-jobclient-2.2.0.jar
hadoop-mapreduce-client-jobclient-2.2.0-tests.jar
hadoop-mapreduce-client-shuffle-2.2.0.jar
hadoop-yarn-api-2.2.0.jar
hadoop-yarn-client-2.2.0.jar
hadoop-yarn-common-2.2.0.jar
hadoop-yarn-server-common-2.2.0.jar
hadoop-yarn-server-nodemanager-2.2.0.jar
