Subject [jira] [Created] (HBASE-16706) Allow users to have Custom tags on Cells
Date Mon, 26 Sep 2016 06:24:20 GMT
Anoop Sam John created HBASE-16706:

             Summary: Allow users to have Custom tags on Cells
                 Key: HBASE-16706
                 URL: https://issues.apache.org/jira/browse/HBASE-16706
             Project: HBase
          Issue Type: Improvement
            Reporter: Anoop Sam John
            Assignee: Anoop Sam John
             Fix For: 2.0.0

The Codec based strip of tags was done as a temp solution not to pass the critical system
tags from server back to client. This also imposes the limitation that Tags can not be used
by users. Tags are a system side feature alone. In the past there were some Qs in user@ for
using custom tags. 
We should allow users to set tags on Cell and pass them while write. Also these custom tags
must be returned back to users (Irrespective of codec and all). The system tags (like ACL,
visibility) should not get transferred btw client and server. And when the client is run by
a super user, we should pass all tags (including system tags). This way we can make sure that
all tags are passed while replication and also tool like Export gets all tags.
