无法从 java 连接到 hbase

Question

我已经设置好一切，就像 hbase 文档说的那样。这是我的 hbase-site.xml

<configuration>
    <property>
        <name>hbase.rootdir</name>
        <value>file:///users/urijvoskresenskij/hbase-0.94.3/hbase</value>
    </property>
    <property>
        <name>hbase.zookeeper.property.dataDir</name>
        <value>/users/urijvoskresenskij/hbase-0.94.3/zookeeper</value>
    </property>
</configuration>

Java 代码：

import java.io.IOException;

import org.apache.hadoop.conf.Configuration;
import org.apache.hadoop.hbase.HBaseConfiguration;
import org.apache.hadoop.hbase.client.HBaseAdmin;
import org.apache.hadoop.hbase.client.HTable;
import org.apache.hadoop.hbase.client.Put;
import org.apache.hadoop.hbase.util.Bytes;

public class MainHBase {

    /**
     * @param args
     */
    public static void main(String[] args) throws Exception {
        Configuration config = HBaseConfiguration.create();
        config.set("hbase.zookeeper.quorum", "localhost");
        HBaseAdmin admin = new HBaseAdmin(config);
        try {
            HTable table = new HTable(config, "test-table");
            Put put = new Put(Bytes.toBytes("test-key"));
            put.add(Bytes.toBytes("cf"), Bytes.toBytes("q"), Bytes.toBytes("value"));
            table.put(put);
        } finally {
            admin.close();
        }
}

这里是个例外：

已经尝试谷歌它，但无法找到解决方案。我的操作系统是 OS X。我尝试创建的表无法从 hbase shell 扫描。请帮忙:)

Answer 1

您是否创建了“测试表”？在将数据放入其中之前，表必须存在。

Configuration conf = HBaseConfiguration.create();
HBaseAdmin hbase = new HBaseAdmin(conf);
HTableDescriptor desc = new HTableDescriptor("test_table");
HColumnDescriptor cf = new HColumnDescriptor("cf".getBytes());
desc.addFamily(cf);
hbase.createTable(desc);
