ramkrishna.s.vasudevan updated HBASE-8496:
------------------------------------------

    Attachment: HBASE-8496.patch

Patch that work with HFile V3 and makes Tags in memory to the KV.  The attached 
design doc is about having Tags in the KV byte array.
We had tried both the options and the attached patch is with inmemory Tags 
rather than appending to the KV byte array.  There are few pros and cons with 
both the approaches.  The support for PerfEval and LoadTestTool will attach in 
a seperate JIRA.  

Many thanks to Anoop for his quality ideas/contributions and review.  
Thanks to Andy for his inputs for the prototypes and reviews.

Pls provide your suggestion/feedback.
