Remove `_all` mapping from older indexes

Elastic Stack Elasticsearch
1

Upgraded to v6.8 recently; trying to ensure I can now upgrade to v7.x Having an issue when trying to reindex my old logstash indexes created on v5.6.x - getting this message when the system goes to create the new index (using the "7.0 Upgrade Assistant" thru Kibana):

[mapper_parsing_exception] [include_in_all] is not allowed for indices created on or after version 6.0.0 as [_all] is deprecated. As a replacement, you can use an [copy_to] on mapping fields to create your own catch all field.

Is there a way to get rid of the _all mapping on the current indexes? (Sorry, have been running ELK stack for a while, but never dug deep into Elasticsearch... getting my education now!) Or, how else could I handle this error?

Looks like I also have a similar issue with Logstash writing to ES as well --

[2022-01-24T13:35:37,059][WARN ][logstash.outputs.elasticsearch] Could not index event to Elasticsearch. {:status=>400, :action=>["index", {:_id=>nil, :_index=>"logstash-2022.01.24", :_type=>"doc", :routing=>nil}, #<LogStash::Event:0x5d051aa4>], :response=>{"index"=>{"_index"=>"logstash-2022.01.24", "_type"=>"doc", "_id"=>nil, "status"=>400, "error"=>{"type"=>"mapper_parsing_exception", "reason"=>"Failed to parse mapping [_default_]: [include_in_all] is not allowed for indices created on or after version 6.0.0 as [_all] is deprecated.

Is this some kind of template issue?

Welcome to our community! :smiley:

What's your index template look like for the Logstash indices?

I listed the templates I have on my system, and I see this:

So I see the "logstash" one has a 'version' from v5.0; If I list this template, I see it does indeed have the _all field, included from the (now-deprecated) _default_ mapping

          "norms" : false
        },

                  }
                }

            }
          }
        ],
        "properties" : {

          },
          "@version" : {
            "type" : "keyword",

              },
              "longitude" : {
                "type" : "half_float"
              }
            }
          }
        }
      }
    },
    "aliases" : { }
  }
}

Ok, try stopping Logstash, deleting that template and then restarting Logstash.

This seems to have done the trick; saw this in Logstash startup messages:

[2022-01-24T20:01:50,431][INFO ][logstash.outputs.elasticsearch] Using default mapping template
[2022-01-24T20:01:50,487][INFO ][logstash.outputs.elasticsearch] Attempting to install template {:manage_template=>{"template"=>"logstash-*", "version"=>60001, "settings"=>{"index.refresh_interval"=>"5s"}, "mappings"=>{"_default_"=>{"dynamic_templates"=>[{"message_field"=>{"path_match"=>"message", "match_mapping_type"=>"string", "mapping"=>{"type"=>"text", "norms"=>false}}}, {"string_fields"=>{"match"=>"*", "match_mapping_type"=>"string", "mapping"=>{"type"=>"text", "norms"=>false, "fields"=>{"keyword"=>{"type"=>"keyword", "ignore_above"=>256}}}}}], "properties"=>{"@timestamp"=>{"type"=>"date"}, "@version"=>{"type"=>"keyword"}, "geoip"=>{"dynamic"=>true, "properties"=>{"ip"=>{"type"=>"ip"}, "location"=>{"type"=>"geo_point"}, "latitude"=>{"type"=>"half_float"}, "longitude"=>{"type"=>"half_float"}}}}}}}}
[2022-01-24T20:01:50,601][INFO ][logstash.outputs.elasticsearch] Installing elasticsearch template to _template/logstash

Now when I list the templates, the logstash one looks better:

root@logstash01:~# curl -XGET http://localhost:9200/_cat/templates?v
name                          index_patterns             order      version
--{snip}--
logstash                      [logstash-*]               0          60001

Thanks!
