Found Error when install the CDP Trial Version

[#1]

Dear Cloudera Community,

Please help, I found the errors when install the CDP Trial Version,

The error messages like these :

https://cdn.redhat.com/content/eus/rhel/server/7/7Server/x86_64/sat-tools/6.6/os/repodata/repomd.xml: [Errno 14] HTTPS Error 404 - Not Found

Trying other mirror.

One of the configured repositories failed (Red Hat Satellite Tools 6.6 (for RHEL 7 Server - EUS) (RPMs)),

and yum doesn't have enough cached data to continue.

At this point the only safe thing yum can do is fail.

failure: repodata/repomd.xml from rhel-7-server-eus-satellite-tools-6.6-rpms: [Errno 256] No more mirrors to try.

https://cdn.redhat.com/content/eus/rhel/server/7/7Server/x86_64/sat-tools/6.6/os/repodata/repomd.xml: [Errno 14] HTTPS Error 404 - Not Found
END (1)
remote package openjdk8 could not be installed, giving up

Hi @Bender 

Hi Ferenc,

1. To overcome the  Error “message “Null value(s) passed to lookup by non-nullable natural-id”

I add  the ip and hostname to these files  :

  /etc/hostname

xxx.xxx.xx.xx     test.testing.com

 /etc/hosts

127.0.0.1          localhost localhost.localdomain localhost4 localhost4.localdomain4

xxx.xxx.xx.xx  test.testing.com     test

 /etc/sysconfig/network :

NETWORKING=yes

NETWORKING_IPV6=no

HOSTNAME= test.testing.com

2. For "Error 404 command has no file attached" message .

It occurs when I run Inspect Network Performance,

Does it occur when you change the scope by any chance? No

Do you get the expected results apart from the error message displayed, please?

It will show the message

 “Insufficient hosts in cluster Cluster 1.Cluster must have at least 2 hosts to run performance inspector.”

Regards,

BSST

Hello @BSST ,

thank you for the more detailed report. Checking internally if we can re-produce.

Kind regards:

Ferenc

Hello @BSST ,

thinking it through my impression is that the agents are not able to reach the server and vice versa.

The screenshot shows that CM is waiting for the CM agent to heartbeat in, which doesn’t happen.

Did you completed this step in [1], please?

"Firewalls (such as iptables and firewalld) must be disabled or configured to allow access to ports used by Cloudera Manager, CDH, and related services."

Another possibility is that SELinux is enabled. [1] points out that "Security-Enhanced Linux (SELinux) must not block Cloudera Manager or CDH operations"

Please check the CM agent logs that would assist to find the root cause. 

Thank you:

Ferenc

Hi @Bender 

I have disabled the firewall and selinux with these messages :

[root@localhost selinux]# systemctl status firewalld
● firewalld.service - firewalld - dynamic firewall daemon
Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)
Active: inactive (dead)
Docs: man:firewalld(1)

[root@localhost selinux]# sestatus
SELinux status: disabled

But I don't know about how to configured to allow access to ports used by Cloudera Manager, CDH, and related services ?

Regards,

BSST

[#6]

Hello @BSST ,

thank you for letting us know that you need clarification on how to set the ports used by CM and related products.

Please see our "Ports Used by Cloudera Runtime Components" documentation [1] that hopefully covers your enquiry.

Kind regards:

Ferenc

Hello @BSST  ,

thank you for sending the agent logs. Based on this because of some reason the agent cannot connect to the CM server.:

[07/Jun/2020 09:30:46 +0000] 1182 MainThread agent ERROR Heartbeating to 192.168.1.8:7182 failed.
error: [Errno 111] Connection refused

You will need to troubleshoot the connectivity between the agent node and the CM Server node and if the port is listening on the CM node.

• What does the CM Server log shows at this period of time, please? (/var/log/cloudera-scm-server/cloudera-scm-server.log [1]). Do you see any exception there?
• Did you follow all the steps one-by-one in our documentation?
• This issue can be caused by multiple reasons e.g. even if the agent is configured for TLS, but the CM Server is not:
  • Network problem, the CM Server is now on another node (check the IP address), certificate issues.
  • Check if the CM Server has enough heap dedicated. Too low heap will result JVM to turn into heavy GC activity, rendering it unresponsive causing timeouts.

Please let us know if you managed to overcome this issue.

Kind regards:

Ferenc

I also encountered a similar problem

My firewall and selinux have been turned off

Try to modify the host name and several configuration files according to the original method, but it still doesn't work

Hello @5sdba ,

thank you for reporting the issue you hit. Can you please specify the CDP version you are using and if you are using CM HA (Cloudera Manager High Availability), please?

Thank you:
