Daryn Sharp commented on HDFS-3627:
-----------------------------------
bq. Also, while the OEV tool does have a binary processor to create the edits
file from an XML textual dump, the OIV tool does not, so for my understanding,
no other changes are required.
A few issues/questions:
# Most important: It appears this patch may break the ability for the OIV to
convert from xml back to a binary image?
# For consistency, I think the other human-readable OIV output formats should
similarly decode a delegation key. It looks like {{IndentedImageVisitor}} may
be the only one.
# It'd be nice for the OEV to also decode the delegation key instead of
printing the class name. This appears to require a similar change in
{{FSEditLogOp.UpdateMasterKeyOp.toXml/fromXml}}.
As an aside, I'm somewhat surprised the xml encode/decode isn't common between
OIV/OEV, but I'm not suggesting any changes there.
