Hi, This PR introduces the Federated Lookup Table as a first step for supporting Federated Multi Tenancy. The Federated Lookup Table maps a Coordinator Identifier (FedUniqueCoordID) to an individual ExecutionContextMap at the Federated Worker. Each Federated Worker creates a FederatedLookupTable, and selects the corresponding ExecutionContextMap per FederatedRequest depending on the coordinator host (obtained from the netty channel) and the pid added to the FederatedRequest. Therefore, it allows the local sequential variable ID creation at the coordinator without collisions with any other coordinators, since every different coordinator has its own ExecutionContextMap. I also added some shell scripts to test the Setup with multiple coordinators locally, although I will most likely change the tests again in a later PR, since I'm not happy with them myself. :D Thanks for review :) -- This is an automated message from the Apache Git Service.
