Description

This JIRA is to add a test case which exhaustively tests double-failure scenarios in a 3-node quorum setup. The test instruments the RPCs between the client and the JNs, and injects faults, simulating a dropped RPC. The framework used by this test will also be expanded in future JIRAs for other failure scenarios.
