Konstantin Shvachko commented on HDFS-4849:
-------------------------------------------

Hey guys. Before we go deeper. If there are no objections about making create idempotent,
I would like to repurpose this jira for create (append) only. And open a new one for delete.
How's that sound?

> create, append and delete operations can be made idempotent. This will reduce chances
for a job or other app failures when NN fails over.
