-------------------------------------
Priority: Major (was: Minor)
> ScanQuery ignore readFromBackups
> --------------------------------

> Key: IGNITE-8288
> URL: https://issues.apache.org/jira/browse/IGNITE-8288
> Project: Ignite
> Issue Type: Bug
> Reporter: Alexander Belyak
> Priority: Major
>
> 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()
> GridCacheQueryAdapter
