HBase安装配置
HBase安装配置
1. 在某一台上解压hbase的压缩文件
tar -zxvf hbase-1.2.3-bin.tar.gz
2. 配置添加环境变量：
#hbase
export HBASE_HOME=/usr/tools/hbase-1.2.3
export PATH=$PATH:$HBASE_HOME/bin
使环境变量生效
source /etc/profile
3. 进入hbase的conf目录，需要修改三个文件：hbase-env.sh、hbase-site.xml和regionservers
其中hbase-env.sh中，在文档的十多行位置处添加：
# The java implementation to use. Java 1.7+ required.
# export JAVA_HOME=/usr/java/jdk1.6.0/
export JAVA_HOME=/usr/tools/jdk1.8.0_73
# Extra Java CLASSPATH elements. Optional.
# export HBASE_CLASSPATH=
然后在后面添加：
# Seconds to sleep between slave commands. Unset by default. This
# can be useful in large clusters, where, e.g., slave rsyncs can
# otherwise arrive faster than the master can service them.
# export HBASE_SLAVE_SLEEP=0.1
# Tell HBase whether it should manage it's own instance of Zookeeper or not.
export HBASE_MANAGES_ZK=false
hbase-site.xml中
The directory where the snapshot is stored.
false: standalone and pseudo-distributed setups with managed Zookeeper
true: fully-distributed with unmanaged Zookeeper Quorum (see hbase-env.sh)
regionservers文件中添加各个从属服务器的ip或者hostname：
centos128
centos129
centos130
4. 保存后分别把hbase的整个文件夹拷贝到其他服务器：
scp -r /usr/tools/hbase-1.2.3 root@centos129:/usr/tools/
scp -r /usr/tools/hbase-1.2.3 root@centos130:/usr/tools/
5. 在hadoop的namenode节点上启动hbase服务
start-hbase.sh
启动后：jps
HRegionServer
HMaster
子节点
HRegionServer
