无法启动钻取:线程"main“org.apache.drill.exec.exception.DrillbitStartupException:中的异常无法获取规范主机名

Question

在kubernetes集群中运行Apache drill时，启动后会抛出此异常：

Starting drillbit, logging to /opt/drill/log/drillbit.out
Exception in thread "main" org.apache.drill.exec.exception.DrillbitStartupException: Could not get canonical hostname.

aks-nodepool1-20640609-1是运行容器的节点的名称。

除Drill之外的所有其他应用程序都可以在此堆栈上正常运行。如何解决这个问题...？

看起来InetAddress.getLocalHost().getCanonicalHostName()无法获得规范的主机名，你可以调查为什么会发生这种情况，也许你需要在你的环境中配置一些东西。另一种选择是使用自定义主机名，它可以使用环境变量进行设置：DRILL_HOST_NAME -> System.getenv("DRILL_HOST_NAME")。
