ramkrishna.s.vasudevan commented on HBASE-15076:
------------------------------------------------
AFter seeing the code
{code}
protected RegionScanner getScanner(Scan scan, List<KeyValueScanner>
additionalScanners,
boolean copyCellsFromSharedMem) throws IOException {
{code}
This API is called by
{code}
public RegionScanner getScanner(Scan scan, boolean copyCellsFromSharedMem)
throws IOException {
{code}
And am not very sure why the need of additionalScanners came when it is not
exposed also. May be am missing something here.
> make the HRegion.getScanner(Scan scan, List<KeyValueScanner>
> additionalScanners, boolean copyCellsFromSharedMem) to be public

> HRegion method getScanner(Scan scan, List<KeyValueScanner>
> additionalScanners, boolean copyCellsFromSharedMem) is protected.
> In Apache Trafodion, we need to invoke this getScanner method from a
> coprocessor. Since it is protected, Trafodion must overload the HRegion class
> and overload this method into a public method.
> It will be good to make this method public.
> It is very useful when one needs to combine several scan result in a single
> scanner.
> thanks,
