we are testing with wget VIA port 8088 the connection from ResourceManager02 to ResourceManager01
- both Resource Managers are part of YARN service , and each resource manager service installed on RHEL 7.9 version
as the following
wget http://ResourceManager01.ggtp:8088

You have new mail in /var/spool/mail/root
as we can see above we have errors as HTTP request sent, awaiting response... 302 Found
and actually the connection take 2-3 min instead of 1 second
is it possible to debug this behavior , and why wget not reached the connection to machine - ResourceManager01 ?
we are perform this testing because we have problem about the connection between secondary ResourceManager02 to primary resources manager - ResourceManager01,
both resources manager are part of Hadoop cluster ( HDP 2.6.5 version )
and from Ambari UI we get the following alert
Connection failed to http://ResourceManager01.ggtp:8088 (timed out)
