FAQ
Hello Experts,

I have couple of questions regarding the management services provided by
Cloudera Manager (Enterprise Edition)

1) What are the best practices for installing these services on a
production cluster? All services on the same master node or distributed
across master nodes and any best practice regarding the co-location for
these services .

2) Any recommendation regarding the use of the database for these services.
We are currently planning to use embedded postgresql.

3) Also while using CM should the host report to the cm server using the
data network or the management network.

Thanks in advance!
Romit.

    Hi Romit,

    I would suggest that you are safe to co-locate the Cloudera Manager
    services on the CM server up to a size of 40-50 nodes. At that point, you
    might consider relocating some/all of the services to a dedicated machine.
    When you get into the 100's, we could advise splitting the services out
    onto individual machines as well

    Postgres, MySQL, and Oracle are all supported. All should work for you, so
    you can select whichever you are most comfortable with.

    I would think the management network - but will defer to other CM experts
    if they might disagree.

    Cheers,
    Adam

    Hi Romit,

    If you decide to go with Postgresql, please update the postgresql.conf file
    as per our recommendation in section "Configuring PostgreSQL Settings"
    here:
    https://ccp.cloudera.com/display/ENT4DOC/Installing+and+Configuring+an+External+PostgreSQL+Database

    Management services insert a lot of data in database and thus database need
    to be tuned for high write throughput.
