NearCache is designed to store small portion of frequently used data [1] of
non-local partitions.

Client can have only LOCAL cache and NearCache that is frontend to
partitioned, see [1]. Moreover, client node requires live server node in
topology.
However, you can try to force "server" mode on client node (via
*TcpDiscoverySpi.setForceServerMode(true)*) to start it without any servers
and use LOCAL cache with read-through.
