> Storage Policy ID is currently not logged in the NN edit log during file creation as
part of {{AddOp}}. This is okay for now since we don't have an API to set storage policy during
file creation.
> However now that we have storage policies, for HDFS-6581 we are looking into using the
feature instead of adding a new field to the INodeFile header. It would be useful to have
the ability to save policy on file create.
