https://community.cloudera.com/t5/Support-Questions/cloudera-manager-does-not-start/m-p/281490#M209410 <P>Hi&nbsp;<a href="https://community.cloudera.com/t5/user/viewprofilepage/user-id/35725">@Nima</a>&nbsp;,</P> <P>&nbsp;</P> <P>Are you sure Cloudera Manager service is down? Did you try to access Cloudera Manager UI to confirm? From the screenshot you posted, it looks like the CM server is active and running. The "error" message in regarding to log was reported internally as the bug #OPSAPS-51665 and it is still under investigation. However, the bug should not cause any issues and seems to be benign.</P> <P>&nbsp;</P> <P>Please try to do: netstat -an | grep 7180 to confirm whether the port is listening. Also, try to access CM UI via: http://&lt;cm-server&gt;:7180</P> <P>&nbsp;</P> <P>Thanks,</P> <P>Li</P> <P>&nbsp;</P> Mon, 28 Oct 2019 18:02:32 GMT lwang 2019-10-28T18:02:32Z
