Hyperledger Fabric：'Orderer'具有无效键：EtcdRaft

Question

当使用官方Hyperledger repo中的configtx.yaml时，我们在尝试创建一个genesis块时会出现以下错误：

我们怎么解决这个问题呢？

Answer 1

解决方案是删除EtcdRaft部分，因为在Hyperledger Fabric v1.3或1.4中尚未实现基于Raft的共识。回购中的configtx.yaml不应该有此部分。

SampleMultiNodeEtcdRaft:
    <<: *ChannelDefaults
    Capabilities:
        <<: *ChannelCapabilities
    Orderer:
        <<: *OrdererDefaults
        OrdererType: etcdraft
        EtcdRaft:
            Options:
              TickInterval: 500ms
              ElectionTick: 10
              HeartbeatTick: 1
