--------------------------------------
Summary: AlreadyClosedException: this IndexReader is closed in
Cluster Query
Key: IGNITE-12895
URL: https://issues.apache.org/jira/browse/IGNITE-12895
Project: Ignite
Issue Type: Bug
Affects Versions: 2.7.6
Reporter: André Schäfer
A simple text query like
{code:java}
var query = new TextQuery<ID, ENTITY>(type,
parse(search.getQuery())).setPageSize(search.getMaxResults());
try (final var cursor = cache.getCache(cacheName).query(query)) {
return stream(cursor).map(Entry::getValue).collect(toList());
}
{code}
in our 6 node setup produces in 3-5 log messages on ERROR level but seem to
deliver a correct result set anyway. It seems that the "remote" searches may be
performed on a closed index reader for some unknown reason.
{code}
