Hamed Madani updated HBASE-8946:
--------------------------------
Attachment: HBASE-8946-v4.patch
I uploaded the new patch with modified comment for closeScanner. I was not sure
how to address your last comment about the test [~larsgeorge]. As I mentioned
*scanId* is an undefined value with *getScannerResults* function. However, if
I'm still missing something please let me know before making 0.94 patch
> Add a new function to Thrift 2 to open scanner, get results and close scanner
> -----------------------------------------------------------------------------

> 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.
