错误:启动嵌入式钻头失败: java.io.IOException(Ubuntu)

Question

我正在尝试启动Apache-drill，但是我仍然面临着这个错误。我怎么才能弄清楚呢？

Error: Failure in starting embedded Drillbit: java.io.IOException: Failed to bind to 0.0.0.0/0.0.0.0:8047 (state=,code=0)

我试着像下面这样编辑drill-override.conf文件。我又收到了同样的错误！

drill.exec: {
  cluster-id: "drillbits1",
  zk.connect: "localhost:8048"
}

此外，您还可以看到netstat命令的结果：

~$ netstat -tlnp | grep 8047

tcp6      11      0 :::8047                 :::*                    LISTEN      12801/java


:~$ netstat -tlnp | grep 8048

Amin，我认为您需要在您的配置中显式地设置Drill使用的端口。配置参数是drill.exec.http.port。

有关如何设置配置的更多详细信息，请查看此处的文档：https://drill.apache.org/docs/ports-used-by-drill/和此处的：https://drill.apache.org/docs/start-up-options/。
