Vinod Kumar Vavilapalli commented on MAPREDUCE-5275:
----------------------------------------------------
I just verified again and it IS public in 1.x.
If and when 'it changes soon', you can remove it and mark it as incompatible at
that point of time.
Even so, the API is taking in a 'namenode', so it can be supported even for
viewfs.
