>             Project: Ignite
>          Issue Type: Bug
>    Affects Versions: 2.4
>            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.
> This happen because in IgniteCacheProxyImpl.query(ScanQuery, IgniteClosure, 
> ClusterGroup) we create GridCacheQueryAdapter 
> (=ctx.queries()createScanQuery...) without pass readFromBackups flag into 
> includeBackups in GridCacheQueryAdapter, and, moreover, in  
> GridCacheQueryManager.scanQueryLocal(GridCacheQueryAdapter, boolean) we 
> create scanIterator not padyint attention to this flag if partition is set.
