    Description

      In test IgniteCacheClientQueryReplicatedNodeRestartSelfTest we have 4 data nodes with replicated caches and single client-only node, which runs SQL queries against those data nodes. Background threads restarting data nodes. When we restart 2 of 4 data nodes everything is fine, when 3 of 4 then eventually query returns inconsistent result and cache size returns smaller values than expected. Since we use rebalance mode SYNC, such a data loss should not happen.
