Alexander Belyak updated IGNITE-8288:
-------------------------------------
Description:
1) Create partitioned cache with backups and readFromBackup(false) on 2+ nodes
cluster
2) Select some partition N, local node should not be primary of partition N
3) execute: cache.query(new ScanQuery<>().setLocal(true).setPartition(N))
Expected result:
empty result (probaply with logging smth like "Trying to execute local query
<query> by primarypartitions with non pridmary local partition N") or even
throw exception
Actual result:
executing (with ScanQueryFallbackClosableIterator) query on local node ignoring
readFromBackups flag.
Problem is that we execute query on backup partitions even if readFromBackups
explicitly set to false.
Same behaviour can be achieved if we get empty node list from
GridCacheQueryAdapter.node() by any reasons, for example - if we run "local"
query from non data node from given cache (see
GridDiscoveryNamager.cacheAffinityNode(ClusterNode node, String cacheName) in
GridcacheQueryAdapter.executeScanQuery()
