             Summary: Add expiration for long time vacant scanners
                 Key: HBASE-26629
                 URL: https://issues.apache.org/jira/browse/HBASE-26629
             Project: HBase
          Issue Type: Improvement
            Reporter: Yutong Xiao
            Assignee: Yutong Xiao


In thrift1 implementation, the ThriftHBaseSerivceHandler holds a Cache with an expire time after access. This will make the long time vacant scanners be collected by gc. However, in thrift2 we do not have this feature and only use a map to store scanners and we need the client close the scanner manually. If not, the expired scanners will live in memory forever. In this case, I applied the cache expiration to thrift2 service.
