Metric aggregation fails in composite aggregation #28688
Description
Hi!
I'm using Elasticsearch to store test results of a software. I'm running Elasticsearch on Docker CE with the following configuration:
Docker version 17.12.0-ce, build c97c6d6
Ubuntu 14.04.5 LTS 14.04 trusty
docker.elastic.co/elasticsearch/elasticsearch-oss:6.2.1
docker.elastic.co/kibana/kibana-oss:6.2.1
The documents look like the following:
{
"product":{
"software":{
"revision":"251ebc1ed721622f49c5485068f8b39c45005a20",
"date":"2018-02-09T17:40:34+00:00"
},
"os":{
"name":"Ubuntu",
"version":"14.04"
}
},
"results":{
"summary":{
"Pass":2,
"Fail":3
}
}
}
I want to compute the average Pass and Fail numbers for all combinations of os.name and os.version for their newest software version, so I use the following Composite query:
GET _search
{
"size": 0,
"query": {
"match_all": {}
},
"aggs": {
"products": {
"composite": {
"sources": [
{
"osName": {
"terms": {
"field": "product.os.name.keyword"
}
}
},
{
"osVer": {
"terms": {
"field": "product.os.version.keyword"
}
}
}
]
},
"aggs": {
"revision": {
"terms": {
"field": "product.software.revision.keyword",
"order": {
"SWDate": "desc"
},
"size": 1
},
"aggs": {
"SWDate": {
"max": {
"field": "product.software.date"
}
},
"Pass": {
"avg": {
"field": "results.summary.Pass",
"missing": 0
}
}
}
}
}
}
}
}
However, this fails with:
"_shards": {
"total": 6,
"successful": 1,
"skipped": 0,
"failed": 5,
"failures": [
{
"shard": 0,
"index": "test_results",
"node": "<nodeId>",
"reason": {
"type": "illegal_state_exception",
"reason": "Cannot replay yet, collection is not finished: postCollect() has not been called"
}
}
]
}
If I remove the Pass average aggregation it does not fail but id does fail with other metric aggregations. Any ideas what I might do wrong? Thanks!
