Additionally there will be changes in how tags are propogated to ranger 
in that whilst today you just associate a tag (classification) with an 
entity, it's more useful often to associate the classification with a 
business term, and then associate that with the entity.

The changes up from the core atlas, will go through a new API 
(ATLAS-1696) and changes in ranger  (RANGER-1454) - if approved (this is 
still work in progress/unreviewed thus far), so feel free to engage in 
the discussions there too.

In terms of in general inheriting the classification ... overrides will 
IMO be needed (as David mentions) since sometimes a derived table will 
require the same classification, for example around confidentiality, 
whilst other times data could be combined and need a HIGHER 
classification whilst in other cases data may be redacted, requiring a 
LOWER classification ;-)


Can be tags inherited?

2017-07-12 Thread Peter Gergo Barna
Hi All,
I have a question about the possibility of Atlas automatically apply tags based 
on lineage relations.

Let's suppose we have a hive table tagged as 'secret'.
Can we have Atlas automatically apply this tag on all entities derived form 
this table, e.g. all views selecting from this table?
Kind Regards
