Vyacheslav Koptilin commented on IGNITE-11986:
----------------------------------------------
Well, it seems a class-path issue. The log file from the server node gives a
hint:
> InvalidClassException: javax.cache.configuration.MutableConfiguration; local
>class incompatible: stream classdesc serialVersionUID = 201405, local class
>serialVersionUID = 201306200821
This class `javax.cache.configuration.MutableConfiguration` is part of
`cache-api` jar, and it looks like that the client node uses the old version of
this library.
Apache Ignite uses version 1.0.0. Please make sure that only one version is
used in the cluster.
