我写的是简单的＆＃34;你好世界＆＃34;使用Java API for HBase的应用程序。这是我的代码：
public static void main(String[] args) throws IOException {
Configuration conf = HBaseConfiguration.create();
conf.set("hbase.zookeeper.quorum", "localhost");
conf.set("hbase.zookeeper.property.clientPort", "2181");
HTable table = new HTable(conf, "myTable");
Scan s = new Scan();
s.addColumn(Bytes.toBytes("a"), Bytes.toBytes("b"));
ResultScanner scanner = table.getScanner(s);
for (Result rr = scanner.next(); rr != null; rr = scanner.next()) {
System.out.println("Found row: " + rr);
}
table.close();
}
结果我得到了：

我在localhost上运行了HBase（版本0.94.14）实例，我不想在分布式模式下，在hdfs等上运行。只需一个实例。我可以通过在浏览器中打开http://localhost:60010/来查看其状态，一切似乎都可以。更重要的是，当我使用不同的应用程序（如Nutch或h-rider）时，一切正常（在HBase的同一个实例中，我尝试连接）。我尝试了不同的选项，例如在hbase-env.sh中设置环境变量$HBASE_HOME或设置export HBASE_MANAGES_ZK=true。在我的应用程序中有相同的版本包含在pom.xml中，所以我可以说没有版本冲突。
<dependency>
<groupId>org.apache.hbase</groupId>
<artifactId>hbase</artifactId>
<version>0.94.14</version>
</dependency>
我的$HBASE_HOME/conf/hbase-site.xml：
<configuration>
<property>
<name>hbase.rootdir</name>
<value>file:///home/bartek/hbase</value>
</property>
<property>
<name>hbase.cluster.distributed</name>
<value>false</value>
</property>
如何让它运行？

试试这个：
public static void main(String[] args) throws IOException, Exception{
Configuration conf = HBaseConfiguration.create();
conf.set("hbase.master", "localhost:60000");
conf.set("hbase.zookeeper.quorum","localhost");
conf.set("hbase.zookeeper.property.clientPort", "2181");
HTable table = new HTable(conf, "mytable");
Get g = new Get(Bytes.toBytes("row1"));
Result result = table.get(g);
byte[]value=result.getValue(Bytes.toBytes("Columnfam1"),Bytes.toBytes("column");
String R = Bytes.toString(value);
System.out.println(R);
table.close();
}

我认为我得到了解决方案，在我的操作系统中禁用IPv6（这里的Ubuntu）有所帮助。它可以像：https://askubuntu.com/a/484487/309788那样完成，但记得重新启动你的系统，在我的情况下，简单的配置是不够的。
