Hi, i try to set the delayed\_timeout variable and have an 503 master timout error. Before that the cluster start to delay tasks:  
`"number_of_pending_tasks" : 127,`

the command I ran was:

`curl -X PUT "localhost:9200/_all/_settings?pretty" -H 'Content-Type: application/json' -d' {"settings": {"index.unassigned.node_left.delayed_timeout": "5m" }}'`

When i check the pending task i found:

> ```
> "tasks" : [
> {
> "insert_order" : 165407269,
> "priority" : "URGENT",
> "source" : "update-settings",
> "executing" : true,
> "time_in_queue_millis" : 522085,
> "time_in_queue" : "8.7m"
> },
> 
> ```

is rare, because its suppose to be rejected...

On the logs of MASTER:

```auto
    [2021-01-22T17:35:10,899][DEBUG][o.e.a.a.i.s.p.TransportUpdateSettingsAction] [CGSS-CLUSTER01-MASTER-2] failed to update settings on indices ...

```

strange...

It would help if you told us a bit more about the cluster and the use case. What is the full output of the [cluster stats API](https://www.elastic.co/guide/en/elasticsearch/reference/7.10/cluster-stats.html)?

Hi Christian, I finally unplugged the master node in charge the moment I ran the command and all pending tasks are gone.  
At the time of this issue, a rolling update from 6.6.0 to 6.8.13 was run.
