Personally, I'm concerned because of the following:
# this will actually increase confusion somewhat among the folks
who have used prior releases of Bigtop
# whatever we do has to be consistent through Bigtop which
means changing all the /etc/<component>/conf locations as well.
That will be quite a bit of work as far as validation is concerned.
Given all of the above, I would appreciate if the benefits of the change
were to be spelled out more clearly. AFAIK, if you deploy Hadoop from
tarballs it doesn't actually assume anything in /etc, since it bundles
all of the configs under the installation tree.
Thanks,
Roman.
