hbase is also based on HDFS. This section is still installed in full distribution mode. Because the time error of each node is too large, the startup of hbase will fail. So the NTP time synchronization service has been installed previously.
Unzip /opt/hbase-1.2.0-cdh5.8.0.tar.gz like hive
tar -zxvf hbase-1.2.0-cdh5.8.0.tar.gz
1. Modify hbase_env.sh under hbase-1.2.0-cdh5.8.0\conf
Add the following configuration
export JAVA_HOME=/usr/java/jdk1.7.0_79
#Declare to use the built-in Zookeeper. Otherwise, you can install a separate Zookeeper
export HBASE_MANAGES_ZK=true
2. Modify the regionservers under hbase-1.2.0-cdh5.8.0\conf
slave1
slave2
That is, the file should be distributed to these two nodes.
3. Configure environment variables
Add to /etc/profile
export HBASE_HOME=/opt/hbase-1.2.0-cdh5.8.0
export PATH=$HBASE_HOME/bin:$PATH
Environment variables take effect
source /etc/profile
4. Configure hbase-site.xml
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
<property>
<name>hbase.rootdir</name>
<value>hdfs://master:9000/hbase</value>
</property>
<property>
<name>hbase.zoopkeeper.property.dataDir</name>
<value>/home/hadoop/software/zookeeper</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.clientPort</name>
<value>2181</value>
<description> The port to connect to zookeeper, the default is 2181</description>
</property>
<property>
<name>hbase.master</name>
<value>master</value>
<description>Specify hbase cluster master node</description>
</property>
<property><name>hbase.thrift.support.proxyuser</name><value>true</value></property>
<property><name>hbase.regionserver.thrift.http</name><value>true</value></property>
</configuration>
5. Copy the /opt/hbase-1.2.0-cdh5.8.0/ directory in the master to slave1, slave2
scp -r /opt/hbase-1.2.0-cdh5.8.0/ hadoop@slave1:/opt
scp -r /opt/hbase-1.2.0-cdh5.8.0/ hadoop@slave2:/opt
6. Start /opt/hbase-1.2.0-cdh5.8.0/bin/start-hbase.sh
master node start
