-------------------------------------------
Summary: Sql. Coordinator failed to send close message after query
cancellation
Key: IGNITE-23457
URL: https://issues.apache.org/jira/browse/IGNITE-23457
Project: Ignite
Issue Type: Improvement
Components: sql
Affects Versions: 3.0.0-beta1
Reporter: Evgeny Stanilovsky
Case: _Query was canceled (for some reason, execution timeout or client side
action) but coordinator failed with sending close message . Need to handle such
a case and just ignore, no recovery actions are needed here, no errors on
client side._
Let`s explain we have a long running query and for some reasons *cancel* is
triggered, directly after two things are happen: 1. coordinator start to send
close message into working nodes 2. one or more nodes become unavailable. On
the basis of our assumptions - NodeLeft event need to be raised but it also can
be raised _after_ message service error. All such cases need to be handled
correctly.
