Root type mapping not empty after parsing

Hi

I am trying to upgrade from ES 0.90.2 to 1.4.0

I am using java api to set the settings of index, this was working fine
with 0.90.2

client.admin().indices().prepareCreate(indexName).setSettings(_).execute().actionGet()

here are my settings:
{
"index": {
"analysis": {
"analyzer": {
"keyword_lowercase": {
"type": "custom",
"tokenizer": "keyword",
"filter": "lowercase"
},
"standard_lowercase": {
"type": "custom",
"tokenizer": "standard",
"filter": "lowercase"
}
}
}
}
}

Getting Root type mapping not empty after parsing error now..
Can you please suggest any solutions?
