@IVenkatesh,

 

Cloudera Manager knows to which database server to connect based on what it sees in /etc/cloudera-scm-server/db.properties

We would not know which server should be used.  It sounds like you'll have to figure out what has changed since you tried "moving" mysql server.

 

If you used to have more users, try accessing each 'scm' database with a mysql client and see what rows exist in the USERS table. That might give you some clues.

I see the cloudera manager is starting afresh and able to login only with user=admin and pwd=admin.we have 2 mysql databases one has amon,hue,mysql,navm,navs,rman databases and second has hive,oozie,scm,sentry.

and /etc/cloudera-scm-server/db.properties is pointing to second mysql database which has hive,oozie,scm,sentry.

Does this need a change to first server ?
