FAQ
Hi,

For some reasons I need to install a cluster with CDH3u2. I am using CM 4.5
on Ubuntu 10.04 (lucid).

I am using the generic debian packages provided by Cloudera and using the
standard package installation from the manager. The problem is that at one
stage of the installation the manager is trying to install the package
'flume-ng'. This package doesn't exist for CDH3u2, there is the flume-node
and flume-master packages.

It looks like a bug to me, probably the 'flume-ng' package is hard coded as
something that is part of the Hadoop environment but there is no
differentiation between the different CDH versions and the different
package names. Is there any way to get around this or I'll have to install
an older CM version that does not have flume-ng in it?

Thanks,

Galed

    Hey Galed,

    Are you seeing installation fail because flume-ng package doesn't exist for
    CDH3u2?

    (CM doesn't support the old flume packages. It only supports flume-ng that
    was available after CDH3u5 and in CDH4.1 and above.)

    Hi Vikram,
    This exactly what happens, which is a bit funny. Because CM supports the
    installation of older CDH versions - I selected the specific version from
    the installation screen. But when it starts to install the packages on the
    agent nodes it's trying to do an 'apt-get install flume-ng', which this
    package does not exist for older versions - and the installation fails...

    Hey Galed,

    You've found a real bug with CM. I've filed an issue internally to take
    care of this. In the meantime, you should follow the instructions for
    manual installation of CDH and CM on
    https://ccp.cloudera.com/display/ENT45DOC/Installation+Path+B+-+Installation+Using+Your+Own+Method

    Sorry for the inconvenience.

    Regards,

    Vikram
