Question

尝试在ubuntu 14.04上安装cloudera时出现以下错误。

subtract

这是创建的日志。

Installation failed. Failed to receive heartbeat from agent.
Ensure that the host's hostname is configured properly.
Ensure that port 7182 is accessible on the Cloudera Manager Server (check firewall rules).
Ensure that ports 9000 and 9001 are not in use on the host being added.
Check agent logs in /var/log/cloudera-scm-agent/ on the host being added. (Some of the logs can be found in the installation details).
If Use TLS Encryption for Agents is enabled in Cloudera Manager (Administration -> Settings -> Security), ensure that /etc/cloudera-scm-agent/config.ini has use_tls=1 on the host being added. Restart the corresponding agent and click the Retry link here.

这就是我目前在etc / hosts中所拥有的;

我的server_host值为localhost，server_port为7182，位于/opt/cloudera-manager/cm-5.7.1/etc/cloudera-scm-agent/config.ini中。我是否需要改变任何事情，请帮助我，我完全没有想法。

Answer 1

netstat -tupnl |grep 19001  \\ default supervisord_port=19001

你会得到这样的结果

tcp   0   0    127.0.0.1:19001   0.0.0.0:*    LISTEN   4833/python

4833 是主管进程ID。终止进程并重新启动cloudera代理。

kill -9 4833
service cloudera-scm-agent restart

如果问题仍然存在，请检查代理日志文件。

Answer 2

ProtocolError： - 我遇到了同样的问题。您可以尝试使用 kill 命令从命令行终止主管。对我有用的另一个修复是删除该特定主机中的cloudera-scm-agent软件包并再次安装。

在ubuntu 14.04上安装cloudera时无法从代理接收心跳
