>
> When sentry server sends response to HDFS, it includes the timestamp of the
> current time at the DB server.
> When sentry client at HDFS gets response from sentry, it sets its local
> variable, which is the latest timestamp received from sentry, to be the
> timestamp in the response
> When sentry client sends request, it should include the latest timestamp
> received from sentry in the request.
