Philip Zeyliger updated HADOOP-6241:
------------------------------------
Attachment: HADOOP-6241-v4.patch.txt
bq. # ./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?
done
bq. 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.
Done. Added another option to specify templates this way.
Also, here's how I've been testing this (still has to be run manually);
{noformat}
$PYTHONPATH=bin:$PYTHONPATH python src/test/bin/split_config_test.py
Could not find template file to place property 'notintemplates'. Ignoring.
