maven - 运行hbase java程序出错

Question

下面是我的 java hbase createtable 程序:-

 public class createtable 
 {

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

  {   
       Configuration conf = HBaseConfiguration.create();    
       conf.set("hbase.zookeeper.quorum", "sandbox.hortonworks.com");
       conf.set("hbase.zookeeper.property.clientPort", "2181");
       conf.set("zookeeper.znode.parent", "/hbase-unsecure");
       HBaseAdmin admin = new HBaseAdmin(conf);
       HTableDescriptor tableDescriptor = new HTableDescriptor(TableName.valueOf("people"));
       tableDescriptor.addFamily(new HColumnDescriptor("personal"));
       tableDescriptor.addFamily(new HColumnDescriptor("contactinfo"));
       admin.createTable(tableDescriptor);
       Put put = new Put(Bytes.toBytes("doe-john-m-12345");     
   }

在我运行命令时创建程序的 jar (table-0.0.1-SNAPSHOT.jar) 之后 hadoop jar table-0.0.1-SNAPSHOT.jar table.createtable

我得到了

   Exception in thread "main" java.lang.NoClassDefFoundError:org/apachehadoop/hbase/HBaseConfiguration at

Answer 1

您的代码无法看到 hbase.jar 。尝试将此部分添加到您的 pom.xml

<!-- https://mvnrepository.com/artifact/org.apache.hbase/hbase -->
<dependency>
    <groupId>org.apache.hbase</groupId>
    <artifactId>hbase</artifactId>
    <version>0.90.2</version>
</dependency>

然后运行它。
