ElasticSearch _reindex 产生“没有这样的索引”

Question

I have two instances of the same version of elasticsearch with the same data.

I am now trying to _reindex an index with:

curl -X POST -H 'Content-Type: application/json' 'localhost:9200/_reindex' -d '{"source": {"index": "my_index_v1"}, "dest": { "index": "my_index_v2" }}'  | jq

On one of the machines, it works correctly and a new index is correctly created. However on second machine, it ends with:

{
  "error": {
    "root_cause": [
      {
        "type": "index_not_found_exception",
        "reason": "no such index [my_index_v2] and [action.auto_create_index] ([.watches,.triggered_watches,.watcher-history-*,.monitoring-*]) doesn't match",
        "index_uuid": "_na_",
        "index": "my_index_v2"
      }
    ],
    "type": "index_not_found_exception",
    "reason": "no such index [my_index_v2] and [action.auto_create_index] ([.watches,.triggered_watches,.watcher-history-*,.monitoring-*]) doesn't match",
    "index_uuid": "_na_",
    "index": "my_index_v2"
  },
  "status": 404
}

I checked the elasticsearch.yml and the file is completely equal on both machines and contains following:

action.auto_create_index: .watches,.triggered_watches,.watcher-history-*,.monitoring-*

I have no idea why this happens.

To be clear, the index really exists.

EDIT:

1. working machine

   • elastic version: 7.17.4
   • settings.json:https://gist.github.com/knyttl/90f5d0f5de194be534160ab729c5a83b

2. non-working machine

   • elastic version: 7.17.4
   • settings.json:https://gist.github.com/knyttl/fcb94cd5739d3626f4545a9b9c5cceef

From the diff it seems that the working machine contains also:

{
  "persistent": {
    "action": {
      "auto_create_index": "true"
    },
    …
  }
}

So I guess that can be the culprit.

Answer 1

Update auto_create_index in second machine as,

{
    "persistent": {
      "action": {
        "auto_create_index": "true"
      }
    }
}

instead of

action.auto_create_index: .watches,.triggered_watches,.watcher-history-*,.monitoring-*

could likely fix the issue.
