Hamed Madani commented on HBASE-8938:
-------------------------------------
>From what I understand , removing the scanner reference from internal map wont
>close the scanner instance itself. Maybe I'm wrong , but I thought
>scanner.close() has to be called to free resources. Looking at thrift 1
>closeScanner function , scanner.close() gets called before removing the
>scannerId from internal map.
> Thrift2 does not close scanner instance
