Na Li commented on SENTRY-2328:
-------------------------------
In case user changes the prefix, will user restart namenode and sentry
services? if so, we don't have issue for this optimization.
> Filter the path information in the fullupdate send to sentry namenode plug-in

> Key: SENTRY-2328
> URL: https://issues.apache.org/jira/browse/SENTRY-2328
> Project: Sentry
> Issue Type: Sub-task
> Components: Sentry
> Affects Versions: 2.1.0
> Reporter: kalyan kumar kalvagadda
> Priority: Major
>
> Currently sentry sends path information of all the HMS objects regardless.
> Instead it should filter them based on the sentry managed prefixes.
> Sending path information of all the HMS objects to sentry namenode plug-in is
> overhead as sentry namenode plug-in ignores entries that not not located in
> the paths managed by sentry. By filtering them at the source we can reduce
> the memory usage and also time to send the full update to sentry namenode
> plug-in.
