Installation failed. Failed to receive heartbeat from agent.

[#1]

I'm trying to install Cloudrea Manager. In the step of Install Agent, I got an error below:

 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.

The log files in /var/log/cloudera-scm-agent/ shows that

------------------------------------------------------------------------------------------------------------------------

Failed to read available parcel file: [Errno 2] No such file or directory: '/var/lib/cloudera-scm-agent/active_parcels.json'

------------------------------------------------------------------------------------------------------------------------

In /var/lib/cloudera-scm-agent/, it's only a file "uuid"

------------------------------------------------------------------------------------------------------------------------

# ll /var/lib/cloudera-scm-agent/
total 4
-rw-r--r--. 1 root root 36 Jul 16 15:25 uuid

------------------------------------------------------------------------------------------------------------------------

Can anyone help me to solve this?

Thanks.

@Roroka,

Since the agent has not been able to heartbeat to Cloudera Manager, it does not know what parcels it needs, so the error you observe regarding "active_parcels.json" is occurring due to an earlier problem.

Can you take a closer look at the cloudera-scm-agent.log to see what the first exception (probably mentions "heartbeat").  If you can include that and 10 or more lines before and after, that should help give us some context for the problem.

If you can, also share with us the output of the following command when run on the host that is not able to heartbeat:

grep -v -e '^[[:space:]]*$' -e '^#' /etc/cloudera-scm-agent/config.ini

Thanks!

@bgooley Thanks for your reply.

Here is more information in the log files.

The error about "heartbeat" appear in the last few lines.

@Roroka,

We need to make sure that your Cloudera Manager configuration matches with the agent configuration.

Based on the below configuration, your agent is configured to use TLS but will perfom no validation of the Cloudera Manager certificate.

In order for a heartbeat to work, then, you would need to have this configured in Cloudera Manager:

You will also need to have configured Cloudera Manager to listen via TLS.

The 'sslv3 alert bad certificate' message indicates that CM did not receive the certificate it expected from the agent (for authentication).  I believe this indicates you have Use TLS Authentication of Agents to Server enabled in CM so CM expects agents will present a certificate.

If you are just installing, though, I would not expect TLS to be involved at all.  Did you enable "Auto-TLS" during installation.  If so, do you have Cloudera Express?

We need more of an understanding of the steps you used to install and also the current configuration of CM.  Also, we need to know what your goal is at this stage and if you were trying to enable TLS in some way...

Thanks!

@bgooley ,

Yes, I enabled "Auto-TLS" during installation and I can't  find the way to disable.

I've uninstall and reinstall again without "Auto-TLS". It can run successfully now.

Thanks for your help!

@Roroka,

I am very glad to hear that you got it working.

The reason I asked about Cloudera Express 6.x is that it does not have support for Auto-TLS.

It is certainly possible to set up TLS manually (our docs cover that).

If you have any questions, this community is a good place to ask.

Cheers.
