windows下hbase eclipse开发环境搭建

1.eclipse中新建普通java工程

2.导入相关jar包

   将HBase解压后根目录下的hbase-0.94.0.jar、hbase-0.94.0-tests.jar和lib子目录下所有jar 包添加到本工程的Classpath下以及hadoop解压根目录下的hadoop-*.jar

3.客户端java程序

	public static void main(String[] args) throws IOException {

          Configuration conf = HBaseConfiguration.create(); 
          //定位到student表
          HTable table = new HTable(conf, "student"); 
          //设置key值 wangwu
          Put put = new Put(Bytes.toBytes("wangwu"));
          //列族info 列age:50 sex:male
          put.add(Bytes.toBytes("info"), Bytes.toBytes("age"),
          Bytes.toBytes("50")); put.add(Bytes.toBytes("info"),
          Bytes.toBytes("sex"), Bytes.toBytes("male"));
          //插入表
          table.put(put);
          table.close();

	}

 4.拷贝Hbase服务器端配置文件hbase-site.xml添加到本工程的Classpath中(src目录下)

<configuration>
	<property>
		<name>hbase.rootdir</name>
		<value>hdfs://hbase服务器ip:9000/hbase</value><!-- 与hbase服务器端配置一样即可 -->
		<description>The directory shared by region servers.</description>
	</property>
	<property>
		<name>hbase.cluster.distributed</name>
		<value>false</value>
		<description>The mode the cluster will be in. Possible values are
			false: standalone and pseudo-distributed setups with managed
			Zookeeper
			true: fully-distributed with unmanaged Zookeeper Quorum (see
			hbase-env.sh)
		</description>
	</property>
	<property>
		<name>hbase.master</name>
		<value>hdfs://hbase服务器ip:60000</value>
	</property>
	<property>
		<name>hbase.zookeeper.quorum</name>
		<value>zookeeper服务器ip</value>
		<description>Comma separated list of servers in the ZooKeeper Quorum.
			For example,
			"host1.mydomain.com,host2.mydomain.com,host3.mydomain.com". By
			default this is set to localhost for local and pseudo-distributed
			modes of operation. For a fully-distributed setup, this should be set
			to a full list of ZooKeeper quorum servers. If HBASE_MANAGES_ZK is
			set in hbase-env.sh this is the list of servers which we will
			start/stop ZooKeeper on.
		</description>
	</property>
	<property>
		<name>hbase.zookeeper.prpperty.clientPort</name>
		<value>2181</value>
	</property>

	<property>
		<name>hbase.zookeeper.property.dataDir</name>
		<value>/home/hadoop/log/zookeeper</value>
		<description>Property from ZooKeeper's config zoo.cfg.
			The directory
			where the snapshot is stored.
		</description>
	</property>
</configuration>

 修改相应的ip地址

5.修改host文件

  hbase服务器端：

  vim /etc/hosts

  本机ip  master

  服务器端的hbase-site.xml中

 

     <property>
		<name>hbase.zookeeper.quorum</name>
		<value>master</value><!--这里不能写ip-->
	</property>

  客户端，即windows下修改hosts文件，配置与服务器端相同

6.运行java程序

     

 INFO zookeeper.ClientCnxn: EventThread shut down

  出现以上这句，说明执行完成，在hbase shell中查看数据插入student表是否成功(以上执行的前提是hbase中已经创建了student表)

 

ps：Will not attempt to authenticate using SASL (无法定位登录配置)

这是由于没有启用用户验证导致的，不影响使用，但影响安全性。SASL 即：Simple Authentication and Security Layer
