Retroactvie install of cloudera manager

Hi,

I have a CDH3 cluster.  Is it straightforward to install cloudera manager onto a live cluster, retroactively?

Thanks,

Presley

@presley: sorry for the delayed response here.  The procedure for overlaying Cloudera Manager onto an existing CDH cluster involves some hands on work as CM needs to rearrange some things a bit.  Eric Sammer previously posted this instruction set out on quora and it's still accurate:

I would recommend that you just take your time to plan it well and know all the steps before starting.
