-------------------------------------
Summary: 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
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?
