date_histogram against empty index results in ArrayIndexOutOfBoundsException

[bsmid]

Hi,

I am using 1.0.0. and see:

{
"error" : "SearchPhaseExecutionException[Failed to execute phase [query], all shards failed; shardFailures {[kwtJyjumSJ-DRx68nXaVhw][data][1]: ArrayIndexOutOfBoundsException[0]}{[kwtJyjumSJ-DRx68nXaVhw][data][0]: ArrayIndexOutOfBoundsException[0]}{[kwtJyjumSJ-DRx68nXaVhw][data][4]: ArrayIndexOutOfBoundsException[0]}{[kwtJyjumSJ-DRx68nXaVhw][data][3]: ArrayIndexOutOfBoundsException[0]}{[kwtJyjumSJ-DRx68nXaVhw][data][2]: ArrayIndexOutOfBoundsException[0]}]",
"status" : 500
}


when running date_histogram query. It happens when I run the query on the whole index while index is empty, or when I run the query on some type which has no documents (while other types in the index have docs).

Steps to reproduce:

curl -XDELETE 'http://localhost:9200/_all/'

curl -XPUT 'http://localhost:9200/data/' -d '{    "mappings" : {
      "_default_" : {
        "_source" : { "enabled" : false },
        "_timestamp" : { "enabled" : true, "store" : true },
        "_all" : {"enabled" : false},
        "properties" : {
          "timestamp" : { "type" : "date", "index" : "not_analyzed", "store": "true" },
          "message" : { "type" : "string", "index" : "analyzed", "analyzer" : "standard", "store": "true" },
          "type" : { "type" : "string", "index" : "not_analyzed", "store": "true" }
        }
      }
    }    
}'

curl "http://localhost:9200/data/_search?fields=*&pretty" -d '{"query":{"filtered":{"filter":{"range":{"timestamp":{"gte":1392026400000,"lte":1392631200000}}},"query":{"query_string":{"query":"mesage:*"}}}},"aggs":{"data":{"date_histogram":{"field":"timestamp","interval":"60m"},"aggs":{"data_type":{"terms":{"field":"_type"}}}}}}'

Hi @bsmid,
This is indeed a bug, but the cause is different than what you describe (also based on your recreation above). It's caused when running a histogram or date_histogram on unmapped fields and then adding a sub-aggregation to them.

In the example above, even though you created a default mapping, you didn't actually index anything and no concrete mappings were created on the index.

In any case... I'll fix it soon...

Thx for reporting!

ps, you can remove the "index" : "not_analyzed" from the timestamp field... this setting only applies to string types

Thx for fixing @uboness !
