I have recently installed cloudera manager on the hadoop environment. I have installed and when i try to run the
service cloudera-scm-agent restartservice cloudera-scm-server restart after changes in vi /etc/cloudera-scm-agent/config.ini.
I am getting the error .. Installation failed.
But when i try to debug the log files, i could see this:
[29/Apr/2020 13:10:09 +0000] 21400 MonitorDaemon-Scheduler __init__ INFO Monitor ready to report: ('HostMonitor',)[29/Apr/2020 13:10:09 +0000] 21400 MainThread agent ERROR Heartbeating to (ipaddress):None failed.Traceback (most recent call last):File "/usr/lib64/cmf/agent/build/env/lib/python2.7/site-packages/cmf-5.16.2-py2.7.egg/cmf/agent.py", line 1434, in _send_heartbeatself.max_cert_depth)File "/usr/lib64/cmf/agent/build/env/lib/python2.7/site-packages/cmf-5.16.2-py2.7.egg/cmf/https.py", line 138, in __init__self.conn.connect()File "/usr/lib64/cmf/agent/build/env/lib/python2.7/site-packages/M2Crypto-0.24.0-py2.7-linux-x86_64.egg/M2Crypto/httpslib.py", line 74, in connectraise errorerror: [Errno 111] Connection refused
But i have set the port number in the ini file:
[General]# Hostname of the CM server.server_host=*ipaddress*
# Port that the CM server is listening on.server_port=7180
I am not able to understand why it is picking none instead of port number. Even am not sure if this is the issue am thinking or some other.
MY ports 7180, 7182,9000 are all open and firewall is disabled too.
Please help me out..
Hi @ruthika ,
Thanks for reaching out to Cloudera community.
The server_port needs to be set to 7182 in the /etc/cloudera-scm-agent/config.ini. CM has an agent heartbeat server which listens on 7182 to accept agent heartbeat.
Please modify the port and then restart CM agent and see if that helps.
Also, please take a look at below doc for the ports used by CM:
Hope this helps!
