> When executing a server function on a partitioned region, if a network hop is done during the execution of the function to access data from another server, the networkHop thread local variable on the PartitionedRegion instance will be set to either 1 or 2. Nevertheless, when the function returns, the variable will not be reset leaving a wrong value in it for subsequent requests.
> As a result, subsequent requests handled by the same thread that executed the previous function will see the networkHop thread local variable with the value set previously by the function no matter if a network hop was required or not. In case of get/put/destroy/invalidate, the server will return this information to the client indicating that it should update the metadata when it should not.
> This will cause unnecessary requests from the client to update the metadata which could impact very negatively the performance of the system.
