hbase

https://hbase.apache.org/

Prerequisites

Get shell script install_java_bin.

Download the java binary packages:

$ curl -LO https://mirrors.tuna.tsinghua.edu.cn/apache/hbase/2.6.1/hbase-2.6.1-hadoop3-bin.tar.gz

Check sum:

$ sha512sum hbase-2.6.1-hadoop3-bin.tar.gz
160d7a79cb21c92101d8e74647477200b541b93d5e75f09648e3a601921119d13f8387beb9f63a9228e67630959227b9ef665d9ac7cbe03e570b7fc4fe1fbfdc  hbase-2.6.1-hadoop3-bin.tar.gz

Install and start hadoop and zookeeper first.

Deploy

Install the java packages on each node:

$ install_java_bin hbase hbase-2.6.1-hadoop3-bin.tar.gz /opt
$ sudo chown ubuntu:ubuntu /opt/hbase

Configure

Edit file /opt/hbase/conf/hbase-env.sh:

 
 # The java implementation to use.  Java 1.8+ required.
 # export JAVA_HOME=/usr/java/jdk1.8.0/
+export $(/usr/bin/env java -XshowSettings:properties -version 2>&1 | grep 'java.home' | sed -e 's/java.home/JAVA_HOME/;s/ //g;')
 
 # Extra Java CLASSPATH elements.  Optional.
 # export HBASE_CLASSPATH=
 # export HBASE_SLAVE_SLEEP=0.1
 
 # Tell HBase whether it should manage it's own instance of ZooKeeper or not.
-# export HBASE_MANAGES_ZK=true
+export HBASE_MANAGES_ZK=false
 
 # The default log rolling policy is RFA, where the log file is rolled as per the size defined for the
 # RFA appender. Please refer to the log4j2.properties file to see more details on this appender.

Edit file /opt/hbase/conf/hbase-site.xml:

   -->
   <property>
     <name>hbase.cluster.distributed</name>
-    <value>false</value>
+    <value>true</value>
   </property>
   <property>
     <name>hbase.tmp.dir</name>
-    <value>./tmp</value>
+    <value>/opt/tmp/hbase</value>
   </property>
   <property>
     <name>hbase.unsafe.stream.capability.enforce</name>
     <value>false</value>
   </property>
+  <property>
+    <name>hbase.rootdir</name>
+    <value>hdfs://las0:9000/hbase</value>
+  </property>
+  <property>
+    <name>hbase.zookeeper.quorum</name>
+    <value>las0,las1,las2</value>
+  </property>
 </configuration>

These files need to be copied to all nodes to the same path.

Edit file /opt/hbase/conf/regionservers:

-localhost
+las0
+las1
+las2

Create the directory of ${hbase.tmp.dir} on each node:

$ sudo mkdir -p /opt/tmp/hbase
$ sudo chown ubuntu:ubuntu /opt/tmp/hbase

Run

Check the version:

$ hbase version
