Marc de Lignie commented on TINKERPOP-1967:
-------------------------------------------
Quite busy at the moment, with other things... I put in a day or so with the
Friendster graph but was not lucky, A single 48Gb machine really could not dig
it (endless spilling for lack of memory). Hortonworks (the software on the
cluster I can access) enriched their hadoop-2.7 with a hadoop-2.9 feature that
made it incompatible with TinkerPop's vanilla hadoop and an attempt to build
TinkerPop with the HDP artifacts proved unsuccesful. I quit the Friendster
graph for now and will do the hopefully easier comparison between the OLTP
query and the connectedComponent() step on a few atificial graphs of increasing
size. If the OLTP query still seems useful, it will not be much work to
contibrute the documentation I prepared. If not, my contribution has not much
added value. I will try to find some time.
