Elasticsearch 1.2.1 exception: Root type mapping not empty after parsing

Question

After updating to Elasticsearch 1.2.1 I keep getting the following exception on the following mapping:

{     "tags": {         "properties": {             "tags": {                 "type": "string",                 "index": "not_analyzed"             }         }     } } 

This is the exception:

Caused by: org.elasticsearch.index.mapper.MapperParsingException: Root type mapping not empty after parsing! Remaining fields: [tags : {properties={tags={index=not_analyzed, type=string}}}]     at org.elasticsearch.index.mapper.DocumentMapperParser.parse(DocumentMapperParser.java:265)     at org.elasticsearch.index.mapper.DocumentMapperParser.parseCompressed(DocumentMapperParser.java:189)     at org.elasticsearch.index.mapper.MapperService.parse(MapperService.java:387)     at org.elasticsearch.index.mapper.MapperService.merge(MapperService.java:253)     at org.elasticsearch.cluster.metadata.MetaDataCreateIndexService$2.execute(MetaDataCreateIndexService.java:363) 

Why is that?

@Mark this appears to be a bug in 1.2.X. There have been multiple others that have reported similar issues, I'll link to the tickets below. Basically it appears that they tightened up on syntax for mappings in 1.2.X but they appear to have caused some problems with previously valid mappings. Yours is one example.

I'd suggest you open a bug report - more power in numbers. Happy to chime in saying "me too" if you open a ticket, as I've recreated the problem on 1.2.1 .

For now I've been able to the following to work which I believe gives you the same desired result:

curl -XPUT localhost:9200/yourindexname -d  '{    "mappings":    {     "tags":       {        "properties":          {           "tags":             {              "type":"string",              "index":"not_analyzed"             }           }         }     } }'

This will help you

you will get want you want to do

curl -XPUT localhost:9200/new_index -d ' {   "mappings": {      "tags": {       "properties": {         "tags": {             "type":"string",            "index":"not_analyzed"         }       }     }   } }' 

or you can also do this way

curl -XPUT localhost:9200/new_index/new_index_type/_mappings -d ' {   "new_index_type": {     "properties": {       "tags": {         "type": "string",         "index": "not_analyzed"       }     }   } }'
