Question

我试图将数据加载到pig中并将相同的数据转储到控制台上。我使用以下命令在Cloudera沙箱中没有任何错误。

raw_data = LOAD 'hdfs:/user/cloudera/sampledata' USING PigStorage(',') AS (
           custno:chararray,
           firstname:chararray,
           lastname:chararray,
           age:int,
           profession:chararray
);

dump raw_data;

它会将所有数据转储到sampledata文件中。

尝试使用以下命令在MapR群集中执行相同的操作。

raw_data = LOAD '/hdfspath/input' USING PigStorage(',') AS (
           custno:chararray,
           firstname:chararray,
           lastname:chararray,
           age:int,
           profession:chararray
);
dump raw_data;

收到以下错误。

请帮助。

先谢谢。

通常，如果您的调度程序在没有分配用户的情况下创建了特定队列，并且提交作业的用户未指定任何队列名称，则会发生这种情况。如果它采用默认队列，并且无权使用它，则最终可能会出现此错误。你可以避免这个问题 export PIG_OPTS =“$ PIG_OPTS -Dmapred.job.queue.name = my-queue” 要么 pig -Dmapreduce.job.queuename = $ queue_name -f path / to / script.pig

java.lang.IllegalArgumentException：没有名为default的队列
