I have a similar issue to this thread ([Anomaly detection - Elastic Jobs failing to start](https://discuss.elastic.co/t/anomaly-detection-elastic-jobs-failing-to-start/220015)).

When I try to start the job packetbeat\_dns\_tunneling, I get the error [datafeed-packetbeat\_dns\_tunneling] cannot retrieve field [dns.question.etld\_plus\_one] because it has no mappings

I ran this command

GET \_ml/datafeeds/datafeed-packetbeat\_dns\_tunneling

and under indices, got the output

"indices": [  
"packetbeat-_",  
"logs-_"  
],

Is this what the job is supposed to map to, or is it supposed to map to something else? packetbeat and logs are where we are getting our logs from.
