Alejandro Abdelnur commented on HDFS-3263:
------------------------------------------

One additional comment regarding how hadoop config files are loaded, the 
current mechanism will easily enable (with minor changes) to have a single 
HttpFS servicing multiple filesystems simultaneously via virtual hosts (the 
hostname would determine with site configs to use). Oozie already has such 
mechanism in place to work with multiple cluster using the config of each one 
of them. I'll open a JIRA for this as well.

> Currently HttpFS reads HDFS client configuration from the httfs-site.xml from 
> any property of the form 'httpfs.hadoop.conf:HADOOP_PROPERTY'
> This is a bit inconvenient.
> Instead we should support a single property 'httpfs.hadoop.configuration.dir' 
> that can be pointed to HADOOP conf/ dir and the core-site.xml and 
> hdfs-site.xml files would be read from there.
