    [ https://issues.apache.org/jira/browse/HBASE-3852?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13650741#comment-13650741 ] 

Lars George commented on HBASE-3852:
------------------------------------

[~jdcryans] The two commits you posted a while back are now gone. Is that still worth looking at or should I just go ahead with what [~bcopeland] attached (plus the minor tweaks suggested)?

> 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).
