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.

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,

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 .

Hi,

 

I am facing the same issue where, cloudera agent is exiting because it is unable to find the supervisord.conf file. The conf file is not getting created. 

 

Error see in cloudera-scm-agent.log file

The cloudera manager and agent version is 5.12.0

 

We did have a server failure and after the reboot of the server, the agent does not start.

 

Ran the below the command:

/usr/lib64/cmf/agent/build/env/bin/python /usr/lib64/cmf/agent/build/env/bin/cmf-agent --package_dir /usr/lib64/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

Please may you help on this? Is the issue fixed in v5.12.2?

To resolve this issue you need to check first all port opened on your server service listing to the port no, use command - sudo netstat -lpten check if any thing is running on 9000 or 90001, mostly java services required for set up is running on port 9000, and cloudera-scm-agent listner also runs on port 9000. to over come this issue you can re-configure theports as well in /etc/cloudera-scm-agent/config.ini by changing as below:-

 

# Hostname of the CM server.
server_host=10.34.156.118

# Port that the CM server is listening on.
server_port=7182

## It should not normally be necessary to modify these.
# Port that the CM agent should listen on.
listening_port=9001

 

It should not normally be necessary to modify these. # Port that the CM agent should listen on 9001

and then restart the cloudera-scm-agent service by command:- $ service cloudera-scm-agent restart TO verify this port is not activated for other sshd service check Ports opened in /etc/ssh/sshd_config.

 

I hope this resolution will work for others too.

Cheers,

Ankit Gupta
