对集群进行 Kerberizing 后，Hortonworks Sandbox 无法启动

Question

我们在 VMware 播放器上使用 HDP 2.3 沙盒，它之前按预期工作。两天前，我使用新的 MIT KDC（安装并在同一个沙箱中启动）对集群进行了kerberized。我可以发出 TGT，一切都按预期工作。

今天我正在尝试启动沙盒并繁荣！它没有启动。我经常看到以下重试消息。 （我已经启动了 KDC 和 kadmin 服务器，并且 root/admin 用户在 klist 中具有有效的 TGT -verified）

Answer 1

192.168.77.137:8020是namenode地址，看起来namenode没有启动。检查那个IP，可能它可能已经改变了，这就是原因。
