Subject Writing visibility labels with HFileOutputFormat2
Date Tue, 07 Jun 2016 10:06:06 GMT

I was wondering if it's possible/how to write Visibility Labels to an HFileOutputFormat2?
I believe Visibility Labels are just implemented as Tags, but with the normal way of writing
them with Mutation#setCellVisibility these are formally written as Tags to the cells during
the VisibilityController coprocessor as we need to assert the expression is valid for the
labels configured.

How can we add visibility labels to cells if we have a job that creates an HFile with HFileOutputFormat2
which is then subsequently loaded using LoadIncrementalHFiles?
