如何使用带环回 IP 地址的主机名配置 Ambari 服务器和 HDP 应用程序？

Question

我在 Ubuntu 12.04 上有一个运行 Ambari 服务器和 HDP 应用程序，主机名解析为 Public IP 地址。我的任务是用环回地址替换 public IP 地址。为此，我做了以下更改：

1) 将 /etc/hosts 文件更新为：
127.0.0.1 本地主机
127.0.0.1 mynode.com 我的节点
#10.xx.xx.xx mynode.com mynode

2) 将以下参数的值设置为“0.0.0.0”使其成为多宿主 dfs.namenode.rpc-绑定主机， dfs.namenode.servicerpc-绑定主机，dfs.namenode.http-绑定主机， dfs.namenode.https-绑定主机，yarn.resourcemanager.bind-主机， yarn.nodemanager.bind-主机，yarn.timeline-service.bind-主机， mapreduce.jobhistory.bind-主机

这些更改后，当我重新启动系统时，HDP 应用程序没有出现。

当我还原在 /etc/hosts 文件中所做的更改以分配 public IP 时，它再次开始正常工作。

我可以知道我还缺少什么吗？

我在 ambari-server.log 文件中看到以下错误：

ERROR [alert-event-bus-2] AlertReceivedListener:365 - Unable to process alert namenode_webui for an invalid service HDFS and component NAMENODE on host localhost ERROR [alert-event-bus-2] AlertReceivedListener:365 - Unable to process alert upgrade_finalized_state for an invalid service HDFS and component NAMENODE on host localhost ERROR [alert-event-bus-2] AlertReceivedListener:365 - Unable to process alert kafka_broker_process for an invalid service KAFKA and component KAFKA_BROKER on host localhost ERROR [alert-event-bus-2] AlertReceivedListener:365 - Unable to process alert storm_supervisor_process for an invalid service STORM and component SUPERVISOR on host localhost ERROR [alert-event-bus-2] AlertReceivedListener:365 - Unable to process alert storm_server_process for an invalid service STORM and component STORM_UI_SERVER on host localhost ERROR [alert-event-bus-2] AlertReceivedListener:365 - Unable to process alert hive_metastore_process for an invalid service HIVE and component HIVE_METASTORE on host localhost ERROR [alert-event-bus-2] AlertReceivedListener:365 - Unable to process alert mapreduce_history_server_process for an invalid service MAPREDUCE2 and component HISTORYSERVER on host localhost ERROR [alert-event-bus-2] AlertReceivedListener:365 - Unable to process alert ams_metrics_collector_process for an invalid service AMBARI_METRICS and component METRICS_COLLECTOR on host localhost ERROR [alert-event-bus-2] AlertReceivedListener:365 - Unable to process alert yarn_resourcemanager_webui for an invalid service YARN and component RESOURCEMANAGER on host localhost ERROR [alert-event-bus-2] AlertReceivedListener:365 - Unable to process alert hive_server_process for an invalid service HIVE and component HIVE_SERVER on host localhost ERROR [alert-event-bus-2] AlertReceivedListener:365 - Unable to process alert storm_drpc_server for an invalid service STORM and component DRPC_SERVER on host localhost ERROR [alert-event-bus-2] AlertReceivedListener:365 - Unable to process alert ams_metrics_collector_autostart for an invalid service AMBARI_METRICS and component METRICS_COLLECTOR on host localhost ERROR [alert-event-bus-2] AlertReceivedListener:365 - Unable to process alert secondary_namenode_process for an invalid service HDFS and component SECONDARY_NAMENODE on host localhost

如能帮助解决此问题，我们将不胜感激。

谢谢。

Answer 1

将这些作为单独的行似乎是问题所在。

127.0.0.1 localhost
127.0.0.1 mynode.com mynode

您可以删除第二行（因为它覆盖了第一行），但建议将它们设为一行

127.0.0.1 localhost mynode.com mynode
