cent0S 7 安装 cdh5.13 笔记之五：

配置 hbase

15 HBase 配置

3台机器上安装了hbase：

n1(cent7-n1.pepstack.com):  hbase-master, hbase-regionserver

n2(cent7-n2.pepstack.com):  hbase-master, hbase-regionserver

n3(cent7-n3.pepstack.com):  -, hbase-regionserver

需要的配置文件如下：

1) backup-masters
2) configuration.xsl
3) hbase-env.sh
4) hbase-site.xml
5) log4j.properties
6) regionservers

下面是配置文件的详细内容：

15.1 backup-masters

cent7-n2.pepstack.com

15.2 configuration.xsl

# 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.

cent7-n2.pepstack.com
cent7-n3.pepstack.com

将上面6个文件复制到所有hbase节点：

/etc/hbase/conf.hacl

然后在所有节点执行：

# alternatives --install /etc/hbase/conf hbase-conf /etc/hbase/conf.hacl 50
# alternatives --set hbase-conf /etc/hbase/conf.hacl
# alternatives --auto hbase-conf

在任何一个namenode上创建hbase目录:

# su - hdfs -c "hdfs dfs -mkdir -p /hbase"
# su - hdfs -c "hdfs dfs -chown hbase /hbase"

启动HBase服务：

n1,n2:

# service hbase-master start

n1,n2,n3:

# service hbase-regionserver start

打开浏览器，输入：

http://cent7-n1.pepstack.com:60010
http://cent7-n2.pepstack.com:60010

HBase安装完毕！
