Cloudera Manager. Agent cannot connect with supervisor. Failed to receive heartbeat from agent

[ Edited ]

Hello all,

 

I've been searching in the forum for this error. I know this is a very common error and I've read a lot of differents posts with related information and solutions. But I still can't solve the problem. I've been trying for two days, and maybe you can help me with something I'm passing through.

 

The point is that I'm trying to install a 3 nodes cluster with Cloudera Manager in Ubuntu 14.04 LTS using the Installation Path A. In the Cluster installation I receive the following error:

 

 

 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.

 

All ports are open. Firewall and SeLinux are deactivated and the following commands with their results are:

hostname

vbigdata0srv.domain.com

 

hostname -f

vbigdata0srv.domain.com

 

python -c 'import socket; print socket.getfqdn(), socket.gethostbyname(socket.getfqdn())'

vbigdata0srv.domain.com 192.168.XXX.XXX (The right IP)

 

*This is the same for  all 3 nodes (vbigdata1srv and vbigdata2srv) with their respective IPs.

 

 

 

The log looks like this, showing as error: ">>[07/Aug/2017 10:25:17 +0000] 10429 MainThread agent ERROR Failed to connect to previous supervisor. "

scm agent started 

 

I tried reinstalling and so on, but I can't solve this. This is second time I try to install Cloudera Manager. First one was in a single node and it went all right at first time.


Anyone have any idea on how to solve this?


Thanks you so much in advance.

Re: Cloudera Manager. Agent cannot connect with supervisor. Failed to receive heartbeat from agent

Hello Josholsan,

 

This stack trace [0] suggests that Cloudera Manager Agent failed to create '/var/run/cloudera-scm-agent/supervisor/supervisord.conf', from past experience the error is often misleading. 

 

To assist us with troubleshooting;

 

On the affected node can you provide the output of the following command;

 

[bash prompt root-user]# /usr/lib/cmf/agent/build/env/bin/python /usr/lib/cmf/agent/build/env/bin/cmf-agent --package_dir /usr/lib/cmf/service --agent_dir /var/run/cloudera-scm-agent --lib_dir /var/lib/cloudera-scm-agent --logfile /var/log/cloudera-scm-agent/cloudera-scm-agent.log --comm_name cmf-agent --pidfile /var/run/cloudera-scm-agent/cloudera-scm-agent.pid

 

Best,

 

Michalis

Re: Cloudera Manager. Agent cannot connect with supervisor. Failed to receive heartbeat from agent

[ Edited ]

Good morning Michalis,

 

this is happening in all my three nodes, they are stuck in the same point. The result for the command you said to me is the following one in al three nodes:

Re: Cloudera Manager. Agent cannot connect with supervisor. Failed to receive heartbeat from agent

[ Edited ]

If running as sudo the results is giving you 

 

OSError: [Errno 13] Permission denied: '/run/user/112/gvfs'

You will need to temporary unmount that tmpfs mount/path, which will allow the Cloudera Manager Agent to start - you are hitting a known issue which will be addressed in the future maintenance release.

 

Regards,

Re: Cloudera Manager. Agent cannot connect with supervisor. Failed to receive heartbeat from agent

Thanks you so much Michalis. Unmount that tmpfs solved the problem for me. This tmpfs is used for something? I mean, shall I mount this after installation?

 

Thanks you so much again! You made my day!!

Re: Cloudera Manager. Agent cannot connect with supervisor. Failed to receive heartbeat from agent

[ Edited ]

The mountpoint isn't part of Cloudera, and likely being mounted by other process in your system. The process that controls the tmpfs mount should be able to remount it again, however you will run into the issue again if you hard_stop the agent. The fix is already been committed and will be available in the next Cloudera maintenance release.

Re: Cloudera Manager. Agent cannot connect with supervisor. Failed to receive heartbeat from agent

Does not the Michalis' provided solution worked for you?

 

In this case:

 

1. Can we see the content of your /etc/hosts file?

2. Can we see the conten of your /etc/hostname file?

3. What are the result of the following commands execution?:

 

-$ hostname

-$ hostname -f

-$ python -c 'import socket; print socket.getfqdn(), socket.gethostbyname(socket.getfqdn())'

 

Any log errors?

 

Thanks.

Re: Cloudera Manager. Agent cannot connect with supervisor. Failed to receive heartbeat from agent

if you have the same error , then the suggest work around is to unmount the "tmpfs " 

To know the location of tmpfs path check your /etc/fstab file you will see the mount point path .
