>          Components: mvcc, sql
>    Affects Versions: 2.7
>            Reporter: Taras Ledkov
>            Assignee: Igor Seliverstov
>            Priority: Major

> If the explicit partitions specified by {{SqlFieldsQuery#setPartitions}} are placed on
the several nodes the query fails at the partition reservation ({{GridDhtTxQueryEnlistFuture.checkPartitions}})
with error: "{{Cannot run update query. Node must own all the necessary partitions.}}"
> *Root cause*: MVCC DML doesn't map the requests {{GridNearTxQueryEnlistRequest}}. Each
node received the messages with all explicit partitions. 
> *Proposal fix*: use the partitions/node mapping similar to SELECT queries. See more:
> - {{GridH2QueryRequest#partitions}}
> - {{ReducePartitionsSpecializer#ReducePartitionsSpecializer}}
