Chris Nauroth commented on HDFS-9055:
-------------------------------------
Hi [~aw]. AFAIK, the only proposed backwards-incompatible change that would
warrant bumping the REST version is the URI handling: HDFS-7822. Is the idea
that v1 and v2 would run concurrently, with the only difference being that
legacy clients could go to v1 for the old non-compliant URI handling, and newer
clients could go to v2? Would v1 and v2 offer the same set of APIs otherwise?
Are there other backwards-incompatible proposals that I've missed?
