hbase的单机搭建

最近准备搭建个单机版的hbase服务器，在apache上下载了hbase的压缩文件，解压后，配置conf文件夹里的三个配置文件，hbase-env.sh;hbase-site.xml;regionservers这三个文件。

hbase-env.sh;

export JAVA_HOME=/usr/local/java/jdk/
# File naming hosts on which HRegionServers will run.  $HBASE_HOME/conf/regionservers by    default.
#export HBASE_REGIONSERVERS=/usr/local/hbase/conf/regionservers


# File naming hosts on which backup HMaster will run.  $HBASE_HOME/conf/backup-masters by default.
#export HBASE_BACKUP_MASTERS=/usr/local/hbase/conf/backup-masters


# Tell HBase whether it should manage it's own instance of Zookeeper or not.
export HBASE_MANAGES_ZK=true

hbase-site.xml;

 
    hbase.rootdir
    /home/hbase
 

regionservers

localhost

在/etc/profile里添加PATH环境变量

export HBASE=/usr/local/hbase

export PATH=$HBASE/bin:$PATH

修改 etc/hosts

添加ip和域名映射

127.0.0.1 localhost

start-hbase.sh

stop-hbase.sh
