    [ https://issues.apache.org/jira/browse/HBASE-3852?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13277955#comment-13277955 ] 

Lars Hofhansl commented on HBASE-3852:
--------------------------------------

In the remove case, should we also close the scanner?

> The scannerMap in ThriftServer relies on the user to clean it by closing the scanner. If that doesn't happen, the ResultScanner will stay in the thrift server's memory and if any pre-fetching was done, it will also start accumulating Results (with all their data).
