> 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?
