在按需群集上运行pig管道作业的故障排除。错误2999：意外的内部错误。 [英] Troubleshooting running a pig pipeline job on on-demand cluster. ERROR 2999: Unexpected internal error.

问题描述

我正在按需HDInsight群集上运行pig管道活动。它几天前成功运行了Azure Blob Storage的输入和输出。但是，从某一点开始，作业始终失败并显示以下消息：

I am running a pig pipeline activity on the on-demand HDInsight cluster. It did successfully ran on the input from and output to both Azure Blob Storage days ago. However, from one point on, the job keep failing with the following message:

19/06/03 01:01:04 ERROR pig.Main: ERROR 2999: Unexpected internal error. String index out of range: 0
19/06/03 01:01:04 WARN pig.Main: There is no log file to write to.

19/06/03 01:01:04 INFO pig.Main: Pig script completed in 239 milliseconds (239 ms)

看起来命令行无法正确读取参数，但我我不知道我到底在哪里应该调查一下。我尝试编辑pig脚本，甚至只是读入并输出相同消息中的数据结果。有关此
错误的任何建议？

It looks like the command line cannot read a parameter correctly, but I'm not sure where exactly are the places I should look into. I tried editing the pig script, even just reading in and output the data results in the same message. Any suggestion on this error?

谢谢！

推荐答案

您好，

当您说"它确实成功运行了Azure Blob Storage的输入并输出到两天前。但是，从某一点开始，作业仍然失败并显示以下消息"，您是否对脚本进行了任何更改。

When you say "It did successfully ran on the input from and output to both Azure Blob Storage days ago. However, from one point on, the job keep failing with the following message", have you made any changes in the script.

要进一步调查，您能否分享完成的步骤与猪脚一起尝试？

To investigate further, could you share the complete steps which you are trying along with the pig script?
