--------------------------------------------
Summary: Prevent starting older node version after upgrade
Key: IGNITE-26751
URL: https://issues.apache.org/jira/browse/IGNITE-26751
Project: Ignite
Issue Type: Improvement
Reporter: Aleksandr Chesnokov
Save node version to local file after each successful start. On startup,
compare current version with saved version. If current version is older than
saved version - crash immediately
An example is given below:
* Start 2.18 -> save 2.18
* Upgrade to 2.19 -> save 2.19
* Node crashes for some reasons
* Try to start 2.18 -> sees saved 2.19 -> crashes because 2.18 < 2.19
It prevents connecting outdated node to updated cluster
