             Summary: add a new function to thrift 2 to open scanner, get results and close scanner
                 Key: HBASE-8946
                 URL: https://issues.apache.org/jira/browse/HBASE-8946
             Project: HBase
          Issue Type: Sub-task
          Components: Thrift
            Reporter: Hamed Madani
         Attachments: HBASE-8946.patch

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.
