Subject Question on writing scan coprocessors
Date Wed, 27 Apr 2016 22:36:17 GMT

I'd like to write a similar coprocessor to the example
RegionObserverExample at
http://www.3pillarglobal.com/insights/hbase-coprocessors  : that is, a scan
coprocessor which intercepts and selectively filters scan results.

My problem is, I need to be able to filter out Results based on a Scan
attribute. preScannerNext() as used in above example does not allow for
this, as Scan object is not passed down to the method.

Any guidance on how to accomplish this?
