------------------------------------------

             Summary: Jest/REST client does not support aliases
                 Key: METAMODEL-249
                 URL: https://issues.apache.org/jira/browse/METAMODEL-249
             Project: Apache MetaModel
          Issue Type: Bug
    Affects Versions: 4.5.2
            Reporter: Dennis Du Krøger


When using an alias for an ElasticSearch index, detectSchema will fail, since we're looking for the mappings of the alias, but ElasticSearch will return the mappings using its real name, at least 1.7.2 in the configuration used by the Danish CVR:

e.g. http://distribution.virk.dk/cvr-permanent/_mapping (sorry, not public) will return this mapping:
{code:javascript}
{
  "cvr-permanent-prod-20151209": {
    "mappings": {
{code}

Since we do {{jestResult.getJsonObject().getAsJsonObject(indexName)}} that will end in an NPE.

I think we'll need to check the aliases mapping to make sure to always use the real index, at least for the getmapping result (if we want to use it for everything including the actual request, we need to make sure that there's no way to block requesting it directly)
