---------------------------------------
[~gvvinblade], the new tests are OK with me.
> MVCC TX: the query with specified explicit patririons fails

> Key: IGNITE-11193
> URL: https://issues.apache.org/jira/browse/IGNITE-11193
> Project: Ignite
> Issue Type: Bug
> Components: mvcc, sql
> Affects Versions: 2.7
> Reporter: Taras Ledkov
> Assignee: Igor Seliverstov
> Priority: Major
> Fix For: 2.8

> Time Spent: 10m

> 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}}
