Hbase伪分布式部署,前提是已经部署好了Hadoop伪分布式,并且已经开启HDFS。

1.下载Hbase

https://mirrors.tuna.tsinghua.edu.cn/apache/hbase/

2.解压,放置/opt/hbase文件下

3.修改配置文件

a.修改配置文件conf/hbase-site.xml

<configuration>
  <property>
        <name>hbase.cluster.distributed</name>
        <value>true</value>
  </property>
  <property>
    <name>hbase.rootdir</name>
    <value>hdfs://localhost:9000/hbase</value>
  </property>
  <property>
    <name>hbase.zookeeper.property.dataDir</name>
    <value>/home/busuanzi/hbase/zookeeper</value>
  </property>
  <property>
    <name>hbase.unsafe.stream.capability.enforce</name>
    <value>false</value>
    <description>
      Controls whether HBase will check for stream capabilities (hflush/hsync).

      Disable this if you intend to run on LocalFileSystem, denoted by a rootdir
      with the 'file://' scheme, but be mindful of the NOTE below.

      WARNING: Setting this to false blinds you to potential data loss and
      inconsistent system state in the event of process and/or node failures. If
      HBase is complaining of an inability to use hsync or hflush it's most
      likely not a false positive.
    </description>
  </property>
</configuration>

b.增加JAVA_HOME,conf/hbase-env.sh

 export JAVA_HOME=/opt/java/jdk1.8.0_172/

4.在HDFS上创建hbase文件夹

hdfs dfs -mkdir /hbase

5.启动hbase

bin/start-hbase.sh

6.检查hbase部署成功

hdfs dfs -ls /hbase

得到如下即成功部署伪分布式hbase

busuanzi@org:/opt/hbase/hbase-2.0.1$ hdfs dfs -ls /hbase
