Rahul Sharma commented on HDT-24:
---------------------------------
I haven't thought on these lines, for now I think connecting to multiple
versions simultaneously looks like a nice to have ! I think it is quite
important that we first sort out the connection to one particular version of
cluster, IMO that will put a good capability in the project. Also I am not sure
how we could facilitate to connect different versions of Hadoop ? somehow embed
different versions of Hadoop (awesome !) or as different connectors for each
version ?
+1 to the idea of having a few sessions and connect to faces !
