> --------------------------------------------------------

> Key: SENTRY-705
> URL: https://issues.apache.org/jira/browse/SENTRY-705
> Project: Sentry
> Issue Type: Bug
> Affects Versions: 1.4.0
> Reporter: Binglin Chang
> Attachments: SENTRY-705.001.patch
>
>
> We are using hive0.13 with sentry, version cdh5.2.0, noticed that hiveserver
> uses lot of memory and doesn't get freed.
> Memory profiling showed that there are lots(millions) of HiveConf and
> HiveAuthzConf instances hold by HiveAuthzBinding.authzBindingMap
> Look at the code, related call order:
> Driver.compile
> HiveAuthzBindingHook.preAnalyze
> HiveAuthzBindingHook.postAnalyze
> hiveAuthzBinding.set
> Driver.execute
> HiveAuthzBindingPreExecHook.run
> hiveAuthzBinding.clear
> Between Driver.compile and Driver.execute, there are too many logic(which
> sentry can not control), not sure hiveAuthzBinding.clear is guaranteed to be
> called
