             Summary: Possible data loss in replicated cache on unstable topology.
                 Key: IGNITE-1027
                 URL: https://issues.apache.org/jira/browse/IGNITE-1027
             Project: Ignite
          Issue Type: Bug
            Reporter: Sergi Vladykin
            Assignee: Yakov Zhdanov
             Fix For: sprint-7


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.
