Anoop Sam John commented on HBASE-16962:
----------------------------------------
For preStoreScannerOpen, we pass the readPnt already
{code}
@Deprecated
KeyValueScanner preStoreScannerOpen(final
ObserverContext<RegionCoprocessorEnvironment> c,
final Store store, final Scan scan, final NavigableSet<byte[]> targetCols,
final KeyValueScanner s) throws IOException;
KeyValueScanner preStoreScannerOpen(final
ObserverContext<RegionCoprocessorEnvironment> c,
final Store store, final Scan scan, final NavigableSet<byte[]> targetCols,
final KeyValueScanner s, final long readPt) throws IOException;
{code}
Am +1 for passing readPnt for the mentioned hook here. With readPnt only it
make full sense of pre hook. There might be other candidates also. Like
preFlushScannerOpen..
May be we can stick to only this method here. Ur call. We wl have to deprecate
old API and add new one.

> Similar to HBASE-15759, I would like to add readPoint to the
> preCompactScannerOpen() API.
> I have a CP where I create a StoreScanner() as part of the
> preCompactScannerOpen() API. I need the readpoint which was obtained in
> Compactor.compact() method to be consistent.
