Question

我正在运行一个map reduce job从Accumulo中的表中获取数据作为输入并将结果存储在Accumulo中的另一个表中。为此，我使用的是AccumuloInputFormat和AccumuloOutputFormat类。这是代码

public int run(String[] args) throws Exception {

        Opts opts = new Opts();
        opts.parseArgs(PivotTable.class.getName(), args);

        Configuration conf = getConf();

        conf.set("formula", opts.formula);

        Job job = Job.getInstance(conf);

        job.setJobName("Pivot Table Generation");
        job.setJarByClass(PivotTable.class);

        job.setOutputKeyClass(Text.class);
        job.setOutputValueClass(Text.class);

        job.setMapperClass(PivotTableMapper.class);
        job.setCombinerClass(PivotTableCombiber.class);
        job.setReducerClass(PivotTableReducer.class);

        job.setInputFormatClass(AccumuloInputFormat.class);

        ClientConfiguration zkConfig = new ClientConfiguration().withInstance(opts.getInstance().getInstanceName()).withZkHosts(opts.getInstance().getZooKeepers());

        AccumuloInputFormat.setInputTableName(job, opts.dataTable);
        AccumuloInputFormat.setZooKeeperInstance(job, zkConfig);
        AccumuloInputFormat.setConnectorInfo(job, opts.getPrincipal(), new PasswordToken(opts.getPassword().value));

        job.setOutputFormatClass(AccumuloOutputFormat.class);

        BatchWriterConfig bwConfig = new BatchWriterConfig();

        AccumuloOutputFormat.setBatchWriterOptions(job, bwConfig);
        AccumuloOutputFormat.setZooKeeperInstance(job, zkConfig);
        AccumuloOutputFormat.setConnectorInfo(job, opts.getPrincipal(), new PasswordToken(opts.getPassword().value));
        AccumuloOutputFormat.setDefaultTableName(job, opts.pivotTable);
        AccumuloOutputFormat.setCreateTables(job, true);

        return job.waitForCompletion(true) ? 0 : 1;
    }

PivotTable是包含main方法的类的名称（也是这个方法）。我也制作了mapper，combiner和reducer类。但是，当我尝试执行此工作时，我收到错误

有人能告诉我这里做错了什么吗？任何帮助将不胜感激。

编辑：我正在运行Accumulo 1.7.0

TApplicationException表示在Accumulo数位板服务器上发生错误，而不是在客户端（MapReduce）代码中发生错误。您需要检查平板电脑服务器日志，以便在TApplicationException {。}}的任何位置获取有关特定错误的详细信息。

通常从ZooKeeper检索表权限，因此它可能表示连接到ZooKeeper的服务器存在问题。

不幸的是，我没有在堆栈跟踪中看到主机名或IP，因此您可能必须检查所有tserver日志才能找到它。

在Accumulo表上运行mapreduce作业时出现TApplicationException异常
