Request hang with alias: Failed to execute fetch phase

[laurent-richer]

Hello,

I'm using the following request which works fine when using index-name in the request :

curl -XGET "http://localhost:9200/ea-v1-2017-06/_search" -H 'Content-Type: application/json' -d'
{
  "version": true,
  "size": 500,
  "sort": [
    {
      "norm_first_techno": {
        "order": "asc",
        "unmapped_type": "boolean"
      }
    }
  ],
  "aggs": {
    "2": {
      "date_histogram": {
        "field": "@timestamp",
        "interval": "30m",
        "time_zone": "Europe/Berlin",
        "min_doc_count": 1
      }
    }
  },
  "query": {
    "bool": {
      "must": [
        {
          "match_all": {}
        },
        {
          "range": {
            "@timestamp": {
              "gte": 1496312222586,
              "lte": 1496398622586,
              "format": "epoch_millis"
            }
          }
        }
      ]
    }
  }
}'

I have created the alias 'ea' which match ea-*.

And now when i'm using the same request with the alias:

curl -XGET "http://localhost:9200/ea/_search ....

Then the curl hang and i've got the following errors in elasticsearch logs:

Any ideas how to fix it ?
