Jean-Daniel Cryans commented on HBASE-3852:
-------------------------------------------
Ah yeah, that commit it here now:
https://github.com/stumbleupon/hbase/commit/985508a185c51b47319541d9d151fcc108a0e590
It's been running in prod for months except that
hbase.thrift.scanner.cleaner.timeout was set down to 180000.
Want me to put it in good shape for review here?
> ThriftServer leaks scanners

> Key: HBASE-3852
> URL: https://issues.apache.org/jira/browse/HBASE-3852
> Project: HBase
> Issue Type: Bug
> Components: Thrift
> Affects Versions: 0.90.2
> Reporter: Jean-Daniel Cryans
> Attachments: 3852.txt, thrift2-scanner.patch
>
>
> 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).
