External Database Setup: Only Reports Manager Requested

[#1]

Hello,

I am installing clouderal manager 5.14 with MySQL as external database.

althought the documentation mention to create diffeenent datbases to host the cloudera manager managment components data as explained here:

https://www.cloudera.com/documentation/enterprise/latest/topics/cm_ig_mysql.html#cmig_topic_5_5

Activity Monitor	amon	amon	amon_password
Reports Manager	rman	rman	rman_password

i choosed custom intsllation to only install the HDFS and YARN

When i did the installation i have only been requested to enter the Reports Mnager database info

I have not been requested to enter data for activity monitor which i believe part of the cloudera manager itself

Appreciate your advise

Hello,

I believe that in most current releases if this is a new installation we do not automatically setup the Activity Monitor Role. This role was originally used by Cloudera Management Services in conjunction with MRv1. If you are not using MRv1 and the Activity Monitor role is not visible in the list of Cloudera Management services then this is the likely reason you have not been prompted to setup and configure the external database for this service in the deployment wizards.

You can check what role instances you have setup by going to:

Cloudera Management Services -> Instances

Hello,

Yes, that is normal. A number of these services have moved towards local file storage mechanisms based on one of a number of different storage formats such as leveldb. Most of these service no longer require an external or embeded database.
