--------------------------------------
Summary: Improve error messages of control script caused by
incompatibility
Key: IGNITE-23387
URL: https://issues.apache.org/jira/browse/IGNITE-23387
Project: Ignite
Issue Type: Task
Reporter: Ilya Shishkov
There are no backward compatibility guaranties for control script, but if you
try to connect to a cluster with older and incompatible version Ignite you will
get (in most cases) uninformative error.
