Hello,   I tried to migrate Cloudera from 5.9 to 5.10. Cloudera Manager Server works well but the agent on the same server doesn't want to start. The cloudera-scm-agent.log shows only this :    [01/Feb/2017 14:35:48 +0000] 3347 MainThread agent INFO SCM Agent Version: 5.10.0 [01/Feb/2017 14:35:48 +0000] 3347 MainThread agent INFO Agent Protocol Version: 4 [01/Feb/2017 14:35:48 +0000] 3347 MainThread agent INFO Using Host ID: 8ec9211f-6612-49f6-b4d5-d2c4fc4e7ada [01/Feb/2017 14:35:48 +0000] 3347 MainThread agent INFO Using directory: /home/cloudera-scm/var/run/cloudera-scm-agent [01/Feb/2017 14:35:48 +0000] 3347 MainThread agent INFO Using supervisor binary path: /home/cloudera-scm/cm-5.10.0/lib64/cmf/agent/build/env/bin/supervisord [01/Feb/2017 14:35:48 +0000] 3347 MainThread agent INFO Neither verify_cert_file nor verify_cert_dir are configured.
