Anoop Sam John commented on HBASE-10311:
----------------------------------------
Actually it will be the same scanner object being passed in next() and next CP
hooks. Yes we already use this VisibilityController. I was about to come
here and suggest this and then saw you realized it alreay on your own.. Good :)
We can not change the CP signature in released major versions. But can change
in Trunk only ( if needed) .. Here it looks not needed at all.. So I will
close this issue.
> Add Scan object to preScannerNext and postScannerNext methods on
> RegionObserver

> Issue Type: New Feature
> Components: Coprocessors
> Affects Versions: 0.96.1.1

>
> I'd like to be able to access the org.apache.hadoop.hbase.client.Scan that
> was used to create a scanner in the RegionObserver.preScannerNext and
> RegionObserver.postScannerNext methods.
> The Scan object is available in the preScannerOpen method, but not in the
> preScannerNext or postScannerNext methods.
> The reason is that I'd like to access the attributes of the Scan object. I
> want to do some resource management in the coprocessor based on some
> attributes of the Scan object (like, who created it).
> Alternatively, does anybody know of another way to get hold of the Scan
> object in these methods without modifying things?
