hbase的安装部署

1.上传安装包，解压，改名

2.配置环境变量

vi /etc/profile
export HBASE_HOME=/usr/local/src/hbase
export PATH=$PATH:$HBASE_HOME/bin

vi hbase-env.sh
export JAVA_HOME=/usr/local/src/jdk1.8
export HBASE_MANAGES_ZK=false


vi hbase-site.xml
<property>
        <name>hbase.rootdir</name>
        <value>hdfs://node:9000/hbase</value>
</property>
<property>
        <name>hbase.cluster.distributed</name>
        <value>true</value>
</property>
<property>
        <name>hbase.master</name>
        <value>node:60000</value>
        <description>指定hbase的master节点</description>
</property>
<property>
        <name>hbase.zookeeper.quorum</name>
        <value>node,node1,node2</value>
        <description>指定zookeeper集群</description>
</property>
<property>
        <name>hbase.zookeeper.property.dataDir</name>
        <value>/export/server/zookeeper-3.4.5/data</value>
        <description>这个路径要与zoo.cfg设置一致</description>
</property>


vi regionservers
node1
node2

4.将hbase表中数据导入到hdfs

hbase org.apache.hadoop.hbase.mapreduce.Export first_table /user/hbase

# first_table   hbase中表名
# /user/hbase   hdfs路径

5.将hdfs中的数据导入到hbase表中

hbase org.apache.hadoop.hbase.mapreduce.Import staff /user/hbase

hbase org.apache.hadoop.hbase.mapreduce.ImportTsv -Dimporttsv.separator='|' -Dimporttsv.columns=HBASE_ROW_KEY,info:info_name,info:info_score1,info:info_score2 first_table /input/student.txt


scan 'first_table',{LIMIT=>10,'FORMATTER'=>'tosSring'}
