Konstantin Boudnik commented on HDFS-4114:
------------------------------------------
I don't understand the rush, guys. There's a legit use of the mechanism as
Konstantin has stated earlier in the JIRA. It might not be widely used at the
moment, but it provides certain benefits to some of us in the community.
Perhaps a certain overhead of maintaining the code is present. Let's see what's
the actual overhead of keeping this code around. BackupImage class had two tiny
patches since February 2013.BackupJournalManager has been touched 5 times in 2+
years. BackupNode was modified 6 times in about the same time, and so on.
Konstantin has repeatedly asked to send all the maintenance issues his way. Why
isn't this a satisfactory approach?
