stack closed HBASE-10311.
-------------------------
Closing at Mr [~neilf]'s suggestion. This seems like something we should doc
in CP section of refguide given two of you fellas bumped into the prob. Let me
try do that and point to this issue.
> Add Scan object to preScannerNext and postScannerNext methods on
> RegionObserver
> -------------------------------------------------------------------------------
>
> Key: HBASE-10311
> URL: https://issues.apache.org/jira/browse/HBASE-10311
> Project: HBase
> Issue Type: New Feature
> Components: Coprocessors
> Affects Versions: 0.96.1.1
> Reporter: Neil Ferguson
> Attachments: HBASE-10311.patch
>
>
> 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?
