Managing configurations

[Mark <st...@gmail.com>]

  What is the preferred way of managing multiple configurations.. ie 
development, production etc.

Is there someway I can tell hadoop to use a separate conf directory 
other than ${hadoop_home}/conf? I think I've read somewhere that one 
should just create multiple conf directories and then symlink the one 
you want to /conf but I was hoping there was more elegant way.

Thanks

You can certainly have the configuration files in any directory, and
use options like --config when launching to specify the alternate
path.

Cloudera installations on Debian systems follow this method. Its
elegant if you use the distro's `update-alternatives` feature to
maintain them.
