Description

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.
