---------------------------------
Epic Link: IGNITE-19577 (was: IGNITE-18528)
> 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
> Priority: Major
> Labels: ignite-3
>
> 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: java.lang.AssertionError
> at
> org.apache.ignite.internal.raft.RaftGroupServiceImpl.randomNode(RaftGroupServiceImpl.java:680)
> at
> org.apache.ignite.internal.raft.RaftGroupServiceImpl.randomNode(RaftGroupServiceImpl.java:667)
> at
> org.apache.ignite.internal.raft.RaftGroupServiceImpl.refreshLeader(RaftGroupServiceImpl.java:222)
> at
> org.apache.ignite.internal.raft.RaftGroupServiceImpl.start(RaftGroupServiceImpl.java:178)
> {code}
> because there are an empty peers on RaftGroupServiceImpl#start. The proper
> solution when a table is created 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.
