By default resource manager runs on port 8088. See if the following takes you to Resource Manager UI.

http://<host where Resource manager is running>:8088

When your YARN is running, Cloudera Manager will show you a tab for "Web UI". Under that tab, there is a link for Resource Manager Web UI. click that and it opens up Resource manager running by default at: http://<host>:8088/cluster

ok thank you but they request to enter a valuer as

resourcemanager.company.com:8032 for Resource Manager

and

resourcemanager.company.com:8030 for Resource Manager Scheduler

Ah! By default this should already be configured. Go to Yarn in Cloudera Manager. click on configuration tab. Under configuration there is on left side a link for "ports and addresses" When you click that it will show you both of these settings.

yarn.resourcemanager.scheduler.address --> set to 8030 by default

yarn.resourcemanager.address --> set to 8032 by default.

i don't have the Cloudera Manager because i work with RAM 6 Bbytes only 😞

you don't need yarn.resourcemanager.hostname because it becomes where ever your resource manager is running. Is it running on localhost? If not, whatever IP address.

I am not sure what the issue is. If you following the directions, then what you are doing is right. you are missing a user name. If this is not working then try adding following to yarns-site .xml (127.0.0.1 may be replaced with localhost assuming that's where resource manager is running)

<code><property>
    <name>yarn.resourcemanager.hostname</name>
    <value>127.0.0.1</value>
</property>

Also I am assuming you already have the following in your yarn-site.xml
<property>
<name>yarn.resourcemanager.address</name>
<value>localhost:8032</value>
</property>
<property>
<name>yarn.resourcemanager.scheduler.address</name>
<value>localhost:8030</value>
</property>
