Todd Lipcon commented on HADOOP-6241:
-------------------------------------
Couple small notes:
- ./bin/split_config.py shows nice usage information including the same
invocation. split_config.py --help lacks the __doc__ info which I found
helpful. Can you convince OptionParser to print that for all usage notices?
- In dist releases, the -default.xml files don't exist. If we expect this to be
useful for users and not just developers, it should be able to look inside the
jars for the -default.xml files. Since jars are just zips, you can probably do
this pretty easily using the zipfile module.
Aside from that, looks good. Sorry I didn't think about the -default thing on
the first pass through.

> This script moves properties from hadoop-site.xml into common-site,
