> In allocateContainer call,  the container is first added to pipelineStateMap and then
added to container cache. If two allocate blocks execute concurrently, it might happen that
one find the container to exist in the pipelineStateMap but the container is yet to be updated
in the container cache, hence failing with CONTAINER_NOT_FOUND exception.
