> Empty data nodes on table creation
> ----------------------------------

> Key: IGNITE-19466
> URL: https://issues.apache.org/jira/browse/IGNITE-19466
> Project: Ignite
> Issue Type: Bug
> Reporter: Sergey Uttsel
> Assignee: Sergey Uttsel
> Priority: Major
> Labels: ignite-3, tech-debt
>
> h3. *Motivation*
> After introducing data nodes from DistributionZoneManager on table creation
> it became possible that a table is created with an empty data nodes value and
> therefore with empty assignments. It causes an exceptions like
> {code:java}
> Caused by: org.apache.ignite.lang.IgniteException: IGN-CMN-65535

> because there are an empty peers on RaftGroupServiceImpl#start. The proper
> solution is a table creation with empty peers but remains unusable until the
> data nodes for the zone is updated and RaftGroupServiceImpl is started with
> peers.
> h3. *Definition of Done*
> If the date nodes for the zone are empty, then create a table without a raft
> group and other components.
> h3. *Implementation Notes*
> In case a table creation when the data nodes values of the zone is empty
> createTablePartitionsLocally method receives an empty newPartAssignment. So
> it is not possible to do startRaftGroupNode without peers. Need to skip start
> a raft group and other components if the data nodes is empty.
