我正在尝试将数据加载到 pig 并将相同的数据转储到控制台。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;

它将所有数据转储到 sampledata 文件中。

尝试使用以下命令在 MapR 集群中执行相同操作。

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。

请提供任何帮助。

通常，如果您的调度程序创建了未分配用户的特定队列，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，您可能会遇到此错误。您可以使用 export PIG_OPTS=”$PIG_OPTS -Dmapred.job.queue.name=my-queue” 或 pig -Dmapreduce.job.queuename=$queue_name -f path/to/script.pig 来避免问题
