-----------------------------------------------------------
Thank [~cmccabe] for the design.
Here are my comments:
To avoiding Hive MetaStore send many duplicate information to Sentry Server, if
Hive side can provide the Hive replication support, it would be good. I think
another solution would be selecting a leader from HiveMetaListeners when Hive
Metastores starting, in sync mode, other listeners must wait the leader finish
sync the metadata to Sentry. After the leader Metastore started, other
Metastore could be back to work.
About Sentry HA, currently sentry server service is stateless, it's better to
keep it stateless and not cover it to active/passive mode, since we have plan
to persist {{Sentry Update Log}} to database. I think sentry servers could
share states by Zookeeper and database.
