Description

I have run into issue where I use a group of Apache Ignite (2.8.1) server nodes in .NET core to create a data grid and run queries to the grid via an Apache ignite java client. I have not problem at all writing data in binary mode to the grid and ask queries via the think layer provided. I use DBeaver to run queries and everything is fine as expected. The issue rise while I am trying to query data from a java client which complains about a conflict in cache ": Conflicts during configuration merge for cache MY_CAHE". Find the error message below:

 

Caused by: class org.apache.ignite.spi.IgniteSpiException: Conflicts during configuration merge for cache 'DOTNET_BINARY_CACHE' :
TRADE conflict:
keyType is different: local=Apache.Ignite.Core.Cache.Affinity.AffinityKey, received=org.apache.ignite.cache.affinity.AffinityKey
