Hi,
The problem: Scroll scan does not return all data. The problem is not
permanent, elasticsearch might return 100% of data or only 50% and it never
throws an exception. A good indicator of the problem is "_shard" section in
the response, e.g.:
"_shards": {"successful": 40, "failed": 0, "total": 50}
In this case 10 shards just refuse to do their job, but the number of
"failed" shards for the same request is different. After looking at the
logs the only info I found is:
[2014-07-24 17:43:49,814][DEBUG][action.search.type ] [i-2722ca77]
Node [6ilkis3hQdO8l4R9nnCA3g] not available for scroll request [...scroll
id removed for readability ...]
Current configuration:
50 shards, 3 replicas, 10 nodes, 650M docs
version 0.90.10
Any ideas what's wrong?
