java.lang.NoSuchFieldError:IBM_JAVA,用于Eclipse中的简单hbase Java客户端

Question

标题是.我的源代码是:

package hbase;

import java.io.IOException;

import org.apache.hadoop.conf.Configuration;
import org.apache.hadoop.hbase.HBaseConfiguration;
import org.apache.hadoop.hbase.HColumnDescriptor;
import org.apache.hadoop.hbase.HTableDescriptor;
import org.apache.hadoop.hbase.client.HBaseAdmin;
import org.apache.hadoop.hbase.util.Bytes;

public class HbaseExampleClient {
public static void main(String[] args) throws IOException {
    Configuration config = HBaseConfiguration.create();
    config.set("hbase.zookeeper.quorum", "192.168.10.17");
    config.set("hbase.zookeeper.property.clientPort", "2222");
    HBaseAdmin admin = new HBaseAdmin(config);//reports an IBM_JAVA NoSuchFieldError
    HTableDescriptor htd = new HTableDescriptor("test1111");
    HColumnDescriptor hcd = new HColumnDescriptor("data");
    htd.addFamily(hcd);
    admin.createTable(htd);
    byte[] tablename = htd.getName();
    HTableDescriptor[] tables = admin.listTables();
    if(tables.length!= 1 && Bytes.equals(tablename, tables[0].getName()))
    {
        throw new IOException("Failed create of table!");
    }
    admin.close();
}
}

    at org.apache.hadoop.hbase.client.HBaseAdmin.<init>(HBaseAdmin.java:116)
    at hbase.HbaseExampleClient.main(HbaseExampleClient.java:19)

看来这个错误与hbase服务器无关,因为我可以正确使用hbase shell.但我真的不知道如何解决这个问题.从我的笔记本电脑(Windows)Eclipse和远程桌面(Ubuntu)linux Eclipse报告同样的错误.

有人可以帮帮我吗？

Answer 1

我也面临同样的问题,但找到了解决方案,由于jar问题,因为IBM_JAVA是常量而发生此问题

 public static final boolean IBM_JAVA = JAVA_VENDOR_NAME.contains("IBM");

并且此常量在类org.apache.hadoop.util.PlatformName中定义,但此包结构和类在两个jar中定义:

1. Hadoop的核心
2. Hadoop的AUTH

但是hadoop-core中存在的类没有这个常数.

IBM_JAVA

你的应用程序试图在hadoop-core jar中搜索.因此,在您的应用程序中添加hadoop-auth jar.
