We have installed Cloudera 5.5. We chose the embedded database during installation. Does anyone have documentation or instructions for migrating the existing database configuratin to a different (new) database (external)?
Is this possible?
Did you manage to solve this? I must also do this migration.
My guess is this one:
- install external PostgreSQL database
- export internal databases via PostreSQL
- import the exported databases via PostgreSQL to the newly installed external db
- reconfigure Cloudera Manager
Please let me know what do you think about it.
Unless Cloudera has a offical way to do this, dm186036'smethod should work. It' all about migrate database from one DB to antoher then configure cm to use the new DB
You may try configure a lab CM machine to use the external DB with imported data first. I think you can switch back to old internal DB if there is an issue, but you should test it first.
