Subject Cell-level security with Coprocessors
Date Fri, 30 Mar 2018 15:27:48 GMT
Hi all,

I'm interested in combining an HBase Coprocessor with cell level 
security.  As a quick example, suppose one wanted to use the 
ColumnAggregation Processor with cells with different authorizations.  
Different users should be able to scan and see the sum of the entries 
that they'd normally be able to scan.

 From the first few hours of looking, it appears that Coprocessors call 
out to the RegionServer's getScanner method which does not apply any 
security by default.

Have others had success combining custom coprocessors with cell-level 
security?  That is, are there any pointers for getting started?

Cheers,

Jim
