> In lazy mode we advance query execution as new page requests arrive. However, method {{GridMapQueryExecutor#onQueryRequest0}} releases partition reservations when only the very first page is processed:
> {code}
> finally {
>     GridH2QueryContext.clearThreadLocal();
>     if (distributedJoinMode == OFF)
>         qctx.clearContext(false);
> }
> {code}
> It means that incorrect results may be returned on unstable topology. We need to release partitions only after the whole query is executed.
