Hadoop2.2.0+Hbase0.96.2分布式集群搭建

最近项目有用到Hbase存储数据,由于现在的hadoop
的集群是基于hadoop2.2.0的,所以不可避免的就需要使用新版的Hbase,以前和hadoop1.x的集群使用的hbase是0.94版本的,现在最新的版本是0.98的,鉴于不稳定,所以散仙就选择了0.96版的Hbase,本次搭建Hbase集群,是基于底层依赖Hadoop2.2.0的,具体的情况描述如下:


序号 机器IP 角色
1 192.168.46.32 Master
2 192.168.46.11 Slave1
3 192.168.46.10 Slave2


本次的集群,散仙使用的是Hbase内置的zk,建议生产环境使用外置的zk集群,具体的配置步骤如下:
序号 描述
1 Ant,Maven,JDK环境
2 配置各个机器之间SSH无密码登陆认证
3 配置底层Hadoop2.2.0的集群,注意需要编译64位的
4 下载Hbase0.96,无须编译,解压
5 进入hbase的conf下,配置hbase-env.sh文件
6 配置conf下的hbase-site.xml文件
7 配置conf下的regionservers文件
8 配置完成后,分发到各个节点上
9 先启动Hadoop集群,确定hadoop集群正常
10 启动Hbase集群
11 访问Hbase的60010的web界面,查看是否正常
12 使用命令bin/hbase shell进入hbase的shell终端,测试
13 配置Windows下的本地hosts映射(如需在win上查看Hbase)
14 屌丝软件工程师一名




hbase-env.sh里面的配置如下,需要配置的地方主要有JDK环境变量的设置,和启动Hbase自带的zk管理:

# In case one needs to do log rolling on a date change, one should set the environment property
# HBASE_ROOT_LOGGER to "<DESIRED_LOG LEVEL>,DRFA".
# For example:
# HBASE_ROOT_LOGGER=INFO,DRFA
# The reason for changing default to RFA is to avoid the boundary case of filling out disk space as 
# DRFA doesn't put any cap on the log size. Please refer to HBase-5655 for more context.

hbase-site.xml里面的配置如下:

regionservers里面的配置如下:
h1
h2
h3

启动后的在Master上进程如下所示:
1580 SecondaryNameNode
1289 NameNode
2662 HMaster
2798 HRegionServer
1850 NodeManager
3414 Jps
2569 HQuorumPeer
1743 ResourceManager
1394 DataNode

关闭防火墙后,在win上访问Hbase的60010端口,如下所示:

在linu的shell客户端里访问hbase的shell如下所示:

至此,我们的Hbase集群就搭建完毕,下一步我们就可以使用Hbase的shell命令,来测试Hbase的增删改查了,当然我们也可以使用Java API来和Hbase交互,下一篇散仙会给出Java API操作Hbase的一些通用代码。
