--------------------------------------
Summary: 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
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
Caused by: java.lang.AssertionError
at
org.apache.ignite.internal.raft.RaftGroupServiceImpl.randomNode(RaftGroupServiceImpl.java:680)

at
org.apache.ignite.internal.raft.RaftGroupServiceImpl.start(RaftGroupServiceImpl.java:178)
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.
