bq. Pardon me Anoop but I don't like the way this is done. This may the only
way to implement it but I'd like to hear argument why so and why we can't
encapsulate the encode/decode in the codec implementation rather than leak
client/server context beyond codec'ing.
I'm fine with holding off the RC until you guys are both good here. Edit: Just
in case the tone doesn't come through the text, I mean there's enough time as
needed to work this into shape as far as I am concerned.

> Project: HBase
> Issue Type: Bug
> Affects Versions: 0.98.0
> Reporter: Anoop Sam John

> Right now we have some inconsistency wrt sending back tags on read. We do
> this in scan when using Java client(Codec based cell block encoding). But
> during a Get operation or when a pure PB based Scan comes we are not sending
> back the tags. So any of the below fix we have to do
> 1. Send back tags in missing cases also. But sending back visibility
> expression/ cell ACL is not correct.
> 2. Don't send back tags in any case. This will a problem when a tool like
> ExportTool use the scan to export the table data. We will miss exporting the
> cell visibility/ACL.
> 3. Send back tags based on some condition. It has to be per scan basis.
> Simplest way is pass some kind of attribute in Scan which says whether to
> send back tags or not. But believing some thing what scan specifies might not
> be correct IMO. Then comes the way of checking the user who is doing the
> scan. When a HBase super user doing the scan then only send back tags. So
> when a case comes like Export Tool's the execution should happen from a super
> user.
> So IMO we should go with #3.
> Patch coming soon.
