错误代码：从 Azure 流分析作业采样数据时出现 BadArgument 错误消息

Question

I tried to take sample data from a running Azure Stream Analytics Job. The job is running successfully and the output is writing into cosmos DB successfully.

But when I tried to take sample data from the streaming input, Sampling is failed and I am getting below error.

Error code: BadArgument
Error message: There was an error while reading sample input. Please check if the input source is configured correctly and data is in correct format.

If it is because of data format, the job should have also failed?

I tried taking sample from another SA job which is using same event Hub but only the difference is, it is using different consumer group, for that I am able to fetch the sample data.

What could be the reason for this failure since the job is working successfully with that input? Is there anything that have to be corrected in consumer group?

Is there any workaround to get sample data from eventhub with some filtering?

Answer 1

This might be happening because the same Event Hub consumer group is being used by different consumers. Try creating a new consumer group for your event hub and configuring your job's input to use this new consumer group.

Answer 2

Now it is working and I am able to take sample from SA job input. Didn't do anything from my end, don't know what exactly was the reason, since it was not working for last one week.
