HBASE簡介
HBASE下載下傳與解壓
下載下傳位址：https://archive.apache.org/dist/hbase/1.2.4/hbase-1.2.4-bin.tar.gz
HBASE各版本位址：https://archive.apache.org/dist/hbase
可使用wget指令來下載下傳：
[email protected]: wget https://archive.apache.org/dist/hbase/1.2.4/hbase-1.2.4-bin.tar.gz
使用tar指令解壓到指定路徑：
[email protected]: sudo tar -zxvf hbase-1.2.4-bin.tar.gz -C /usr/
修改hbase-1.2.4檔案夾的權限
[email protected]: sudo chown -R hadoop:hadoop /usr/hbase-1.2.4
修改HBASE配置檔案
修改hbase-env.sh檔案：
[email protected]:/usr/hbase-1.2.4/conf$ sudo vi hbase-env.sh
添加JAVA_HOME ,并注釋掉部分内容(因為我們使用java1.8及以上版本)：
# The java implementation to use. Java 1.7+ required.
export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-amd64/
# Configure PermSize. Only needed in JDK7. You can safely remove it for JDK8+
###export HBASE_MASTER_OPTS="$HBASE_MASTER_OPTS -XX:PermSize=128m -XX:MaxPermSize=128m"
###export HBASE_REGIONSERVER_OPTS="$HBASE_REGIONSERVER_OPTS -XX:PermSize=128m -XX:MaxPermSize=128m"
修改hbase-site.xml檔案：
[email protected]:/usr/hbase-1.2.4/conf$ sudo vi hbase-site.xml
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl" target="_blank" rel="external nofollow" ?>

<configuration>

<name>hbase.rootdir</name>
<value>hdfs://ubuntu:9000/hbase</value>

<value>/usr/tmp/zookeeper</value>

</configuration>
修改regionservers
[email protected]:/usr/hbase-1.2.4/conf$ sudo vi regionservers
添加 localhost 即可。
由于hbase.zookeeper.property.dataDir配置為/usr/tmp/zookeeper，是以要在/usr下建立tmp檔案夾，并将檔案夾所有者修改為hadoop
[email protected]:/usr$ mkdir /usr/tmp
[email protected]:/usr$ sudo chown -R hadoop:hadoop tmp/
配置環境變量
[email protected]:/usr/hbase-1.2.4/conf$ vi ~/.bashrc
在末尾處添加以下内容：
export HBASE_HOME=/usr/hbase-1.2.4
export PATH=$HBASE_HOME/bin:$PATH
将修改應用于系統：
[email protected]:/usr/hbase-1.2.4/conf$ source ~/.bashrc
啟動服務
注意啟動順序，先啟動 hadoop
[email protected]:/usr/hbase-1.2.4/conf$ start-all.sh
再啟動 hbase
[email protected]:/usr/hbase-1.2.4/conf$ start-hbase.sh
檢視是否啟動成功
[email protected]:/usr/hbase-1.2.4/conf$ jps
出現以下内容即啟動成功
[email protected]:/usr/hbase-1.2.4/conf$ jps
30354 Jps
3763 SecondaryNameNode
4052 NodeManager
4661 HQuorumPeer
4856 HRegionServer
4728 HMaster
3917 ResourceManager
3405 NameNode
3566 DataNode
下面可進入 hbase shell 檢視，輸入 hbase shell，出現hbase工作台
[email protected]:/usr/hbase-1.2.4/conf$ hbase shell
HBase Shell; enter 'help<RETURN>' for list of supported commands.
Type "exit<RETURN>" to leave the HBase Shell

hbase(main):001:0> [email protected]:/usr/hbase-1.2.4/conf$
小結
HBASE 的配置與 hadoop 相比難度還是小了很多的，但如果 hadoop 沒有配置好，在使用HBASE時将會出現一系列出乎意料的問題。
