Josh Elser commented on ACCUMULO-2050:
--------------------------------------
Wow, that's rough -- but, giving some more feedback on the HDFS ticket would
probably be good too :P
I haven't looked at the viewfs stuff at all yet. It seems excessive to
reimplement something whose functionality already (appears) to be in HDFS. Is
delaying viewfs for 1.6 and planning for it in a 1.7 timeline reasonable? This
might actually be mutually agreeable for a few other reasons (things that
didn't make the 1.6 cut).
