Ted Yu commented on HBASE-17182:
--------------------------------
The timestamp can be recorded in the map:
{code}
private int addScanner(ResultScanner scanner) {
int id = nextScannerId.getAndIncrement();
scannerMap.put(id, scanner);
{code}
Each time the scanner is returned:
{code}
private ResultScanner getScanner(int id) {
return scannerMap.get(id);
{code}
The timestamp should be updated.
> Memory leak from openScanner of HBase thrift2
