如何在分佈式模式下本地啓動drillbit？

我下載的Apache鑽V1.8，編輯conf/drill-override.conf有以下變化：如何在分佈式模式下本地啓動drillbit？

drill.exec: { 
    cluster-id: "drillbits1", 
    zk.connect: "10.178.23.140:2181,10.178.23.140:2182,10.178.23.140:2183,10.178.23.140:2184" 
}

..zookeeper集羣有效組成4個動物園管理員實例的開始一樣，一臺機器上，我想開始鑽取。（即我只使用一臺機器爲Apache鑽和動物園管理員的集羣，機器的IP是10.178.23.140）

所以，我不斷收到此錯誤：

Exception in thread "main" org.apache.drill.exec.exception.DrillbitStartupException: Failure during initial startup of Drillbit. 
    at org.apache.drill.exec.server.Drillbit.start(Drillbit.java:295)

爲什麼鑽頭抱怨是綁定到回送地址？！

我沒有配置鑽頭的IP綁定到！
而且由於我在我的機器上啓動鑽頭鑽取過程，我的機器會嘗試綁定哪些其他IP？

的問題是，我/etc/hosts中文件中有這樣的條目

127.0.1.1 mgelbana-machine

這使我的主機名解析爲環回地址。要解決此問題，您可以執行以下任一操作

刪除此行解決了我的問題。
將我的主機名解析爲非回送IP地址。

private void checkLoopbackAddress(String address) throws DrillbitStartupException, UnknownHostException { 
    if (isDistributedMode && InetAddress.getByName(address).isLoopbackAddress()) { 
    throw new DrillbitStartupException("Drillbit is disallowed to bind to loopback address in distributed mode."); 
    } 
}

爲什麼鑽拒絕，同時綁定到環回地址來啓動的原因，是differentiate between Drill nodes registered in Zookeeper.
