I'm currently setting up a machine learning job to detect rare events for host names. However I get the following error on the validation page of the job:
This is the full error:
{
"statusCode": 400,
"error": "Bad Request",
"message": "[illegal_argument_exception: [illegal_argument_exception] Reason: [Bucket max] cardinality estimate required for [influencers] [host.name] but not supplied]: [Bucket max] cardinality estimate required for [influencers] [host.name] but not supplied",
"attributes": {
"body": {
"error": {
"root_cause": [
{
"type": "illegal_argument_exception",
"reason": "[Bucket max] cardinality estimate required for [influencers] [host.name] but not supplied"
}
],
"type": "illegal_argument_exception",
"reason": "[Bucket max] cardinality estimate required for [influencers] [host.name] but not supplied"
},
"status": 400
}
}
}
What causes this error and how can i mitigate it?
Thanks for the help in advance!
