hbase安装配置

环境准备

1. Java
2. HDFS
3. zookeeper
4. SSH，NTP时间同步
5. 系统调优，这个可以等安装完后改，文件打开数（ulimit和nproc）
6. 修改Hadoop HDFS Datanode同时处理文件的上限：dfs.datanode.max.xcievers

---

下载HBASE

http://mirror.bit.edu.cn/apache/hbase/

---

解压设置权限

1.tar -zxf habse.tar.gz -C /usr/local/habse

2.sudo chown -R hadoop:hadoop /usr/local/habse

---

配置conf/hbase-env.sh

#设置JAVA路径及CLASSPATH
export JAVA_HOME=/usr/local/java/jdk1.8.0_121
export JAVA_CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
#设置不让HBASE管理ZK
export HBASE_MANAGES_ZK=false

---

配置conf/hbase-site.xml

<configuration>
	<property>
	<name>hbase.master</name>
	<value>master:60000</value>
	</property>
	<property>
		<name>hbase.master.maxclockskew</name>
		<value>180000</value>
	</property>
	<property>
		<name>hbase.rootdir</name>
		<value>hdfs://master:19000/hbase</value>
	</property>
	<property>
		<name>hbase.cluster.distributed</name>
		<value>true</value>
	</property>
	<property>
		<name>hbase.zookeeper.quorum</name>
		<value>master,slave1,slave2</value>
	</property>
	<property>
		<name>hbase.zookeeper.property.dataDir</name>
		<value>/usr/local/zookeeper/zookeeper-3.4.10/</value>
	</property>
</configuration>

参数说明:

1. hbase.rootdir，HDFS的入口地址，地址和端口要和你的hadoop配置一样（core-site.xml中的fs.default.name），所有节点公用地址
2. hbase.cluster.distributed，ture表示分布式
3. hbase.zookeeper.property.clientPort ， zookeeper端口
4. hbase.zookeeper.quorum ， zookeeper节点
5. hbase.zookeeper.property.dataDir ， zookeeper 保持信息的文件，默认为/tmp 重启会丢失

---

配置conf/regionservers

master
slave1
slave2

---

分发配置好的文件

scp -r hbase/ hadoop@slavex:/usr/local

---

启动&停止HBASE

./bin/start-hbase.sh
./bin/stop-hbase.sh

启动成功后使用jps命令即可看到相关进程

---

查看HABSE日志

1. 在logs目录下可以看到HBASE日志.如果启动不成功可以查看相关log日志中是否报错.

错误[zookeeper.MetaTableLocator: Failed]

一般认为是，停止Hbase服务时导致zookeeper的meta数据丢失或损毁所致，解决办法时，停止HBase服务，停止ZooKeeper服务，把zookeeper的每个节点的zoo.cfg指定的dataDir=/hadoop/zookeeper-data目录的文件清除掉，然后重启zookeeper,再重启hbase,再去观察hbase主控节点日志hbase-hadoop-master-master.log,发现一切正常，问题已经得到解决！

解决第一步错误后master启动成功,slavex报错

查看错误信息后发现是hdfs-site.xml中 hdfs://master;19000/hbase 配置项错误
