## Hbase安装使用 ##

安装环境：MAC OS

#### 一、下载 ####

[http://mirror.bit.edu.cn/apache/hbase/stable/hbase-1.2.6.1-bin.tar.gz][http_mirror.bit.edu.cn_apache_hbase_stable_hbase-1.2.6.1-bin.tar.gz]

#### 二、解压安装 ####

1）解压并进入`hbase-1.2.6.1`目录

tar xzvf hbase-1.2.6.1-bin.tar.gz
    cd hbase-1.2.6.1

2）配置`JAVA_HONE`和打开自带zookeeper参数`HBASE_MANAGES_ZK`，编辑`hbase-env.sh`文件

# The java implementation to use.  Java 1.7+ required.
    export JAVA_HOME=`/usr/libexec/java_home` # Tell HBase whether it should manage it's own instance of Zookeeper or not.
    export HBASE_MANAGES_ZK=true

3）配置hbase数据存储路径，编辑`conf/hbase-site.xml`文件

<property>
        <name>hbase.rootdir</name>
        <value>file:///Users/zhengyong/hbase/database</value>
      </property>
      <property>
        <name>hbase.zookeeper.property.dataDir</name>
        <value>/Users/zhengyong/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>

3) 启动zookeeper

4) 启动hbase

➜  bin ./start-hbase.sh
    starting master, logging to /Users/zhengyong/Development/hbase-1.2.6.1/bin/../logs/hbase-zhengyong-master-zhengyongdeMacBook-Air.local.out
    Java HotSpot(TM) 64-Bit Server VM warning: ignoring option PermSize=128m; support was removed in 8.0
    Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=128m; support was removed in 8.0

5) 使用shell客户端连接hbase

➜  bin ./hbase shell
    2018-08-03 14:40:07,272 WARN  [main] util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable
    HBase Shell; enter 'help<RETURN>' for list of supported commands.
    Type "exit<RETURN>" to leave the HBase Shell
    Version 1.2.6.1, rUnknown, Sun Jun  3 23:19:26 CDT 2018
    
    hbase(main):001:0>

6) 执行命令

hbase(main):001:0> create 'test', 'cf'
    0 row(s) in 1.8050 seconds => Hbase::Table - test
    hbase(main):002:0> list
    TABLE
    test
    1 row(s) in 0.0550 seconds => ["test"]
    hbase(main):003:0> describe 'test'
    Table test is ENABLED
    test
    COLUMN FAMILIES DESCRIPTION
    {NAME => 'cf', BLOOMFILTER => 'ROW', VERSIONS => '1', IN_MEMORY => 'false', KEEP_DELETED_CELLS => 'FALSE',
    DATA_BLOCK_ENCODING => 'NONE', TTL => 'FOREVER', COMPRESSION => 'NONE', MIN_VERSIONS => '0', BLOCKCACHE =>
    'true', BLOCKSIZE => '65536', REPLICATION_SCOPE => '0'}
    1 row(s) in 0.1960 seconds
    
    hbase(main):004:0>

7) Hbase webUI
