----------------------------------------

Can you put this up on RB? Noticed a few nits and whatnot where RB would be easier for review.

> HBASE-11553 abstracted out the VisibilityLabelService and using which one can go with
String based labels tags instead of default ordinal based. In MapReduce side, ImportTSV also
should support such an abstraction layer.  This is applicable for HFileOutputFormat where
mappers create Cells to be written to HFiles. 
> Also every Mapper (custom written also) dealing with such low level HBase things (Creation
of tags and Cells) is not a good idea. This issue plan to provide a public audience Facade
class to facilitate such Cell creation so that Mappers can just make use of them.
