------------------------------------------
Caused by IGNITE-11262
> Discovery Compression check fails when nodes reconnect to cluster
> -----------------------------------------------------------------
>
> Key: IGNITE-11730
> URL: https://issues.apache.org/jira/browse/IGNITE-11730
> Project: Ignite
> Issue Type: Bug
> Components: general
> Affects Versions: 2.7
> Reporter: Ilya Kasnacheev
> Priority: Major
>
> There is a check that Discovery Data Bag compression is supported by all
> nodes.
> Apparently this check does not work when nodes reconnect after server
> restart. When there is at least one client node that does not support this
> feature, clients will still send zipped data that server would not
> understand, leaving to following server error:
> {code}
