Mapping definition has unsupported analyzer (upgrade to 2.0)

Elastic Stack Elasticsearch

I'm upgrading from ES 1.7.1 to ES 2.0.0, before I defined my analyzers in elasticsearch.yml file of ES. The definitions are as below (I also tried index.analysis.analyzer.adefault: instead of indentation):

index: 
  analysis: 
    analyzer: 
      adefault: 
        char_filter: html_strip
        filter: "standard, lowercase"
        tokenizer: standard
        type: custom
      alang1: 
        char_filter: html_strip
        filter: "standard, lowercase, fstopde, fstemde"
        tokenizer: standard
        type: custom
      alang2: 
        char_filter: html_strip
        filter: "standard, lowercase, fstopar"
        tokenizer: standard
        type: custom
      alangen: 
        char_filter: html_strip
        filter: "standard, lowercase, fstopen, fstemen"
        tokenizer: standard
        type: custom
      alangt1: 
        type: german
      alangt2: 
        type: arabic
      alangten: 
        type: english
      angram: 
        filter: "standard, lowercase, fngram"
        tokenizer: standard
        type: custom
      aporterstem: 
        filter: "standard, lowercase, porterStem"
        tokenizer: standard
        type: custom
      asnowball1:

        tokenizer: standard

        min_gram: 2
        type: nGram
      fngramurl: 
        max_gram: 20
        min_gram: 3
        type: nGram
      fstemde: 
        name: minimal_german
        type: stemmer
      fstemen: 
        name: minimal_english
        type: stemmer
      fstopar: 
        stopwords: _arabic_
        type: stop
      fstopde: 
        stopwords: _german_
        type: stop
      fstopen: 
        stopwords: _english_
        type: stop
    tokenizer: 
      tngram: 
        max_gram: 10
        min_gram: 2
        type: nGram

I read my mappings from a file in order to create my index. The file is defined as following:

{
    "files": {
        "properties": {
            "startDate": {
                "type": "date", 
                "format": "yyyy-MM-dd HH:mm:ss:SSS||yyyy-MM-dd HH:mm:ss", 
                "index": "not_analyzed",
                "store": "yes"
            },
            "fileLang1": { 
                "type": "attachment", 
                "index": "yes", 
                "analyzer": "alang1"
            }
        }
    }
}

When I create my index I'm getting the following exception:

MapperParsingException[mapping [files]]; nested: MapperParsingException[Mapping definition for [fileLang1] has unsupported parameters:  [analyzer : alang1] [index : yes]];
Caused by: MapperParsingException[Mapping definition for [fileLang1] has unsupported parameters:  [analyzer : alang1] [index : yes]]

Any ideas what I'm doing wrong? Thanks in advance.

I think I figured it out.

Creating an index is probably much more strict now and some values might have changed, e.g. "index" accepts only three values, and "yes" ain't one of them. (https://www.elastic.co/guide/en/elasticsearch/reference/2.0/mapping-index.html)

I now defined "fileLang1" as following:

"fileLang1": {
    "type": "string",
    "index": "analyzed",
    "analyzer": "alang1"
}

and use a "copy_to" from "content" of an attachment type.

"file": { 
    "type": "attachment", 
    "fields": {
        "title": { "store": true },
        "content_type": { "store": true, "index": "no" },
        "content": { "store": true, "term_vector": "with_positions_offsets", "type": "string", "copy_to": ["fileGrams", "fileEn", "fileLang1", "fileLang2"] },
        "date": { "store": true },
        "author": { "store": true },
        "keywords": { "store": true },
        "content_type" : { "store": true },
        "language": { "store": true }
    }
},

I hope I'm doing this the correct way, if not please let me know.
