> The [DistributedProcess|https://github.com/apache/ignite/blob/master/modules/core/src/main/java/org/apache/ignite/internal/util/distributed/DistributedProcess.java] fails the local node ({{FailureHandler}} CRITICAL_ERROR thrown) if unable to send a message to the coordinator (e.g. the coordinator fails right before the single message is sent).
> {code:java}
>             try {
>                 ctx.io().sendToGridTopic(p.crdId, GridTopic.TOPIC_DISTRIBUTED_PROCESS, singleMsg, SYSTEM_POOL);
>             }
>             catch (IgniteCheckedException e) {
>                 log.error("Unable to send message to coordinator.", e);
>                 ctx.failure().process(new FailureContext(CRITICAL_ERROR,
>                     new Exception("Unable to send message to coordinator.", e)));
>             }
> {code}
> h4. Expected behaviour
> If the {{ClusterTopologyCheckedException}} occurs need to wait for the NODE_LEFT event of the coordinator node and re-init the distributed process future.
