Tom White commented on HADOOP-5670:
-----------------------------------
XInclude from a remote filesystem? I'm worried that XML parsers won't
handle errors well. Perhaps it could be made to work.
There are two pieces to this ticket anyway. 1. read config files from
an arbitrary filesystem. 2. get daemons to re-read config more
dynamically - most of them just do so once at startup. I would have
separate issues for these.
I had some conversations with Doug on this in the summer, but I never
got round to even opening a ticket (!). The idea was to expose ZK as a
Hadoop FileSystem then change Configuration to load from an arbitrary
FS. There is a bootstraping issue to get round too.
