Aaron T. Myers commented on HDFS-6940:
--------------------------------------
{quote}
If I am reading this right, you'd be ok with a potentially huge refactoring of
NN followed by one the two:
1. significant duplication of the NN code in the CNode
2. unnecessarily exposing the implementation of many intimate parts of NN
{quote}
I was not necessarily suggesting any of those things. It's not at all clear to
me that said refactor would necessarily be "huge," or that it would result in
any duplication of NN code in the ConsensusNode. If it's designed well I don't
see why either of those things would necessarily be the case. That very much
remains to be seen, and just asserting that it would be so is not very
constructive.
