> Key: IGNITE-9722
> URL: https://issues.apache.org/jira/browse/IGNITE-9722
> Project: Ignite
> Issue Type: Bug
> Components: cache, mvcc
> Reporter: Andrew Mashenkov
> Assignee: Vladimir Ozerov
> Priority: Critical
> Fix For: 2.7
>
>
> The test make transactional putAll() and then check data with Scan query and
> getAll().
> ScanQuery can miss some results on unstable topology which is expected as it
> doesn't lock topology.
> But getAll() can unexpectedly return stale results.
> To reproduce the issue, one can change read mode SCAN->GET (passed to
> checkAndGetAll() call) in checkPutGet() method.
>
> It looks like rebalance can overwrite local backup entries or remap is broken
> and we read local partition in moving state. Disabling fastLocGet in
> GridPartitionedGetFuture.map() resolves the issue.
