Question

我在独立的cloudera vm上运行Hbase。我只是尝试从我的java代码连接到hbase，但始终获得此异常。我没有在hbase-site.xml中输入任何内容。我也有Hbase和zookeper启动并运行。以下是我得到的例外情况：

这是我的java代码。

public int run(String[] args) throws Exception {
        int result=0;
        String outputPath = args[1];        
        Configuration configuration = getConf();
        configuration.set("data.seperator", DATA_SEPERATOR);        
        configuration.set("hbase.table.name",TABLE_NAME);       
        configuration.set("COLUMN_FAMILY_1",COLUMN_FAMILY_1);       
        configuration.set("COLUMN_FAMILY_2",COLUMN_FAMILY_2);       
        Job job = new Job(configuration);       
        job.setJarByClass(HBaseBulkLoadDriver.class);       
        job.setJobName("Bulk Loading HBase Table::"+TABLE_NAME);        
        job.setInputFormatClass(TextInputFormat.class);     
        job.setMapOutputKeyClass(ImmutableBytesWritable.class);     
        job.setMapperClass(HBaseBulkLoadMapper.class);      
        FileInputFormat.addInputPaths(job, args[0]);        
        FileSystem.getLocal(getConf()).delete(new Path(outputPath), true);      
        FileOutputFormat.setOutputPath(job, new Path(outputPath));      
        job.setMapOutputValueClass(Put.class);      
        HFileOutputFormat.configureIncrementalLoad(job, new HTable(configuration,TABLE_NAME));      
        job.waitForCompletion(true);        
        if (job.isSuccessful()) {
            HBaseBulkLoad.doBulkLoad(outputPath, TABLE_NAME);
        } else {
            result = -1;
        }
        return result;
    }

Answer 1

Zookeeper正在通过localhost解决并连接正常。你能解决quickstart.cloudera吗？我猜这是一个DNS问题，因为调用超时到quickstart.cloudera。那有意义吗？

无法使用java api
