> SENTRY-1508 performs full Sentry HDFS sync at the construction time. Turns
> out, it does not work with Kerberos on, because the Hive code initialized
> Kerberos client only AFTER instantiating MetastorePlugin. Fix is pretty
> straightforward: MetastorePlugin should not attempt synchronization with
> Sentry from the constructor. It should rely on the housekeeping thread's
> SyncTask to ultimately succeed in pushing the first full update. The subtle
> point is that until it happens, all partial updates going through
> MetastorePlugin should skip Sentry notification step while keeping updating
> the MetastorePlugin's local cache as usual.
