> 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.
