             Summary: Client disconnect and coordinator node shutdown failover
                 Key: IGNITE-20851
                 URL: https://issues.apache.org/jira/browse/IGNITE-20851
             Project: Ignite
          Issue Type: Improvement
          Components: compute
            Reporter: Mikhail Pochatkin


h2. Coordinator node shutdown

In the case when the coordinator node is turned off, the execution of the job 
will not stop (except for the case where the worker node and the coordinator 
node coincide), but in this case the client loses the opportunity to receive 
the result of the job execution.
h2. Client disconnect

The current architecture implies that if the connection with the client is 
broken, the execution of the job must be canceled, since there is no way to get 
the result of the job execution.
