Created on ‎04-25-2018 10:38 AM - edited ‎04-25-2018 10:58 AM

After a data center outage, my Cloudera cluster running CDH 5.8.5 was not functioning properly, so I took these steps:

  • Logged into Cloudera Manager which said that host monitors and service monitors were not reachable.
  • SSH-ed into nodes of the cluster, cleared log files for cloudera-scm-agent and supervisord, then attempted to restart cloudera-scm-agent (service cloudera-scm-agent restart)
  • cloudera-scm-agent log is shown below. It indicates a connection refused when connecting to the supervisor process.
  • supervisord produced no new log messages during this time.

Any help would be appreciated here. Thank you!

I also found this output in /var/log/cloudera-scm-agent/supervisord.out. Apparently the supervisord is throwing an import error because of the module diewithparent.

Hi @brandonvin

Try to run

service cloudera-scm-agent hard_stop_confirmed
service cloudera-scm-agent start

Or

service cloudera-scm-agent hard_restart

Good luck.
