estamos testando com wgeta porta VIA 8088a conexão de ResourceManager02paraResourceManager01
- ambos os Resource Managers fazem parte do serviço YARN e cada serviço do Resource Manager é instalado na versão RHEL 7.9
como o seguinte
wget http://ResourceManager01.ggtp:8088

You have new mail in /var/spool/mail/root
como podemos ver acima temos erros como HTTP request sent, awaiting response... 302 Found
e na verdade a conexão leva de 2 a 3 minutos em vez de 1 segundo
é possível depurar esse comportamento e por que wgetnão alcançou a conexão com a máquina ResourceManager01?
estamos realizando este teste porque temos problemas com a conexão entre ResourceManager02o gerenciador de recursos secundário e primário - ResourceManager01,
ambos os gerenciadores de recursos fazem parte do cluster Hadoop (versão HDP 2.6.5)
e da UI do Ambari recebemos o seguinte alerta
Connection failed to http://ResourceManager01.ggtp:8088 (timed out)
