Failed to receive heartbeat from agent while installing cloudera
netstat -tupnl |grep 19001 \\ default supervisord_port=19001
You will get result like this
tcp 0 0 127.0.0.1:19001 0.0.0.0:* LISTEN 4833/python
4833 is Supervisor process id. Kill the process and restart the cloudera agent.
kill -9 4833
service cloudera-scm-agent restart
And check the agent log file if the issue still persists.
