Lars George commented on HBASE-8946:
------------------------------------
Sorry, my bad (too late for me here) :)
One nit, could you extend the test to scan three times, with 5, 10, and 20
rows? Just to check they return 5, 10 and 10 as expected per the test rows?
Also, for some reason the patch does not apply to 0.95, there seems to be a
class that is different to trunk. Would you be able to have a look too?

> We found, very often we open a scanner , get x number of rows , then close
> the scanner immediately. The attached patch , add a new function
> *getScannerResults* that does just that.
> Using getScannerResults function reduce number of calls to thrift server.
> Also since the scanner gets closed immediately, it is less prone to cause
> memory leak.
