org.apache.cassandra.db.context.CounterContext.computeOldShardMerger()
Compute a new context such that if applied to context yields the same total but with old local node ids nulified and there content merged to the current localNodeId.


        assert ctx.total(state.context) == 11;


        try
        {
            ByteBuffer merger = ctx.computeOldShardMerger(state.context, Collections.<NodeId.NodeIdRecord>emptyList(), 0);
            ctx.removeOldShards(ctx.merge(state.context, merger, HeapAllocator.instance), now);
            fail("RemoveOldShards should throw an exception if the current id is non-sensical");
        }
