但是我在quickstart.cloudera这条路径下添加了quickstart.cloudera的ip地址。我在hbase-site.xml文件中使用此名称HBaseConfiguration hc = new HBaseConfiguration( new Configuration( ) );
hc.set("hbase.master", "quickstart.cloudera:60000");
hc.set("hbase.zookeeper.quorum", "quickstart.cloudera");
hc.set("hbase.zookeeper.property.clientPort","2181");
HBaseAdmin admin = new HBaseAdmin(hc);
HTableDescriptor[] tableDescriptor = admin.listTables();
for (int i=0; i<tableDescriptor.length;i++ )
{
System.out.println(tableDescriptor[i].getNameAsString());
}
}
，我在我的eclipse项目中粘贴了该文件。
但是在本地系统中连接时，相同的代码可以正常工我试图运行这个程序，但有些问题。

我的输出：
awk答案 0 :(得分：0)
尝试设置这些配置设置
Configuration conf= new Configuration();
conf.set("fs.defaultFS", "hdfs://" + host + ":"+port);
conf.set("fs.hdfs.impl",
org.apache.hadoop.hdfs.DistributedFileSystem.class.getName()
);
conf.set("fs.file.impl",
org.apache.hadoop.fs.LocalFileSystem.class.getName()
);
HBaseConfiguration hc = new HBaseConfiguration( conf );
