----------------------------------
Summary: Handle ClassNotFoundException during deserialization of
persisted cache configuration
Key: IGNITE-8162
URL: https://issues.apache.org/jira/browse/IGNITE-8162
Project: Ignite
Issue Type: Improvement
Components: general
Affects Versions: 2.4
Reporter: Ivan Rakov
Fix For: 2.6
Ticket is created according to dev list discussion:
http://apache-ignite-developers.2346864.n4.nabble.com/Fwd-Data-Loss-while-upgrading-custom-jar-from-old-jar-in-server-and-client-nodes-td28808.html
Cache configuration is serialized by JDK marshaller and persisted in
cache_data.dat file. It may contain instances of classes that disappeared from
runtime classpath (e.g. implementation of CacheStore has been renamed). In such
case, node will fail on start.
We should handle this and show meaningful message with instruction how to
overcome this issue - delete cache_data.dat and restart cache.
