hbase 安装和使用

下载hbase

配置conf中hbase-env.sh

#Java环境

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_77.jdk/Contents/Home


#通过hadoop的配置文件找到hadoop集群

export HBASE_CLASSPATH=/Users/lihu/hadoop-2.7.2/hbase-1.2.4/conf

#使用HBASE自带的zookeeper管理集群

export HBASE_MANAGES_ZK=true

配置conf中的hbase-site.xml

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>

<configuration>
    <property>
        <name>hbase.rootdir</name>
        <value>hdfs://localhost:9000/hbase</value>
    </property>
    <property>
        <name>hbase.cluster.distributed</name>
        <value>true</value>
    </property>
    <property>
        <name>hbase.zookeeper.quorum</name>
        <value>localhost</value>

创建表t1

 hbase(main):013:0> create 't1',{NAME => 'f1', VERSIONS => 2},{NAME => 'f2', VERSIONS => 2}

查看有哪些表

hbase(main):001:0> list

插入数据没有指定column

hbase(main):003:0> put 't1', 'r1', 'f1', 'v1'

插入数据指定column

hbase(main):007:0> put 't1', 'r4', 'f1:c1', 'v1'

插入多列数据

hbase(main):010:0> put 't1', 'r7', 'f1:c4', 'v9'
hbase(main):011:0> put 't1', 'r7', 'f2:c3', 'v9'

将logs里面的文件删除和hdfs上面的/hbase删除就好了
