Can help to enlighten why I cannot cancel this task

{  
"completed" : false,  
"task" : {  
"node" : "Vzjnc-d2SuOZ07\_6LCyl2A",  
"id" : 4779394,  
"type" : "transport",  
"action" : "cluster:admin/xpack/monitoring/bulk",  
"description" : "",  
"start\_time\_in\_millis" : 1589760017235,  
"running\_time\_in\_nanos" : 960362867263688,  
"cancellable" : false,  
"headers" : { }  
}  
}

{  
"completed" : false,  
"task" : {  
"node" : "Vzjnc-d2SuOZ07\_6LCyl2A",  
"id" : 4779395,  
"type" : "transport",  
"action" : "indices:data/write/bulk",  
"description" : "requests[1], indices[.monitoring-kibana-7-2020.05.18]",  
"start\_time\_in\_millis" : 1589760017237,  
"running\_time\_in\_nanos" : 960423096214079,  
"cancellable" : false,  
"headers" : { }  
}  
}

This system index (.monitoring-kibana-7-2020.05.18) is not exisiting, I can’t even delete

{  
"node\_failures" : [  
{  
"type" : "failed\_node\_exception",  
"reason" : "Failed node [Z40kmKesSmOY-IMH-Duzkw]",  
"node\_id" : "Z40kmKesSmOY-IMH-Duzkw",  
"caused\_by" : {  
"type" : "illegal\_argument\_exception",  
"reason" : "task [Z40kmKesSmOY-IMH-Duzkw:486196425] doesn't support cancellation"  
}  
}  
],  
"nodes" : { }  
}

Hi, it looks like this is a system task from the Elasticsearch Task Management API: [https://www.elastic.co/guide/en/elasticsearch/reference/current/tasks.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/tasks.html). The Elasticsearch Discuss category is the place for information / help on this.

It would also help to use code formatting for the JSON, and include any error messages / what you have started out trying to do.

Thanks!

I was trying to cancel through the \_cancel API but didn't work.

Since this isn't a Kibana topic, the readers and team members here may not be able to give you the best help for this issue around the Elasticsearch API. Try asking over at [https://discuss.elastic.co/c/elastic-stack/elasticsearch/6](https://discuss.elastic.co/c/elastic-stack/elasticsearch/6)

Hope this helps,
