Na Li commented on SENTRY-2121:
-------------------------------
"Another option is to always trigger a full snapshot every time HDFS sync is
enabled"
Sentry has no way to know HDFS is just enabled, or it is enabled since last
restart of services.
> Notifications processed during times when HDFS sync is disabled will not be
> applied as ACLs when later HDFS sync was to be enabled

> When HDFS sync is disabled, we don't update the AUTHZ_PATHS_MAPPING table.
> However, when HDFS sync is enabled, ACLs that are generated are based on
> entries in the AUTHZ_PATHS_MAPPING table. So this means that if we were to
> disable HDFS sync and later enable HDFS sync, ACLs for all notifications that
> were processed during the times when HDFS sycn was disabled won't be created
