Problem Description
In #111863 the TransportAbstractBulkAction was using ThreadPool::relativeTimeInNanos to get the start time, and then subtracting that from the ThreadPool::relativeTimeInNanos of the finish time to compute the took time. Given the ThreadPool::relativeTimeInNanos is updated by a fixed thead in 200ms interval by default. So the took time was not correct (sometimes it's even 0) as expected in standalone Elasticsearch cluster.
Steps to Reproduce
Open an elk standalone cluster. Using the command like below.
PUT /bulk-took-test
PUT /bulk-took-test/_bulk
{ "index" : { "_index" : "bulk-took-test", "_id" : "1" } }
{ "field1" : "value1" }
The response could be the json like below. And the took time is zero.
{
"errors": false,
"took": 0,
"items": [
{
"index": {
"_index": "bulk-took-test",
"_id": "1",
"_version": 1,
"result": "created",
"_shards": {
"total": 2,
"successful": 1,
"failed": 0
},
"_seq_no": 0,
"_primary_term": 1,
"status": 201
}
}
]
