Chris K Wensel commented on HADOOP-4117:
----------------------------------------
well, it might be safer to have the script chmod the file on the server when
pushed up to init.d.
i'll chmod the file locally and try testing the scripts again tonight and see
if it carries over scp reliably.

> Currently hadoop-site.xml for EC2 instances is stored as a part of the image
> and only a few properties can be controlled from the user scripts
> (compression, number of map/reduce tasks). Furthermore, it is not possible to
> rsync the configuration around the EC2 cluster with the current image, so the
> only way to customize the hadoop-site.xml file is to rebuild the image, which
> is time-consuming.
> It would be much better to pass the initialization script for nodes at boot
> time, so that it is easy to edit the configuration before starting a cluster.
