Some comments below on the blog below -- I haven't watched the video yet.
 I think this is very good.

>>> "Sentry currently uses a file-based policy provider. And, you can link
a global policy file to multiple dependent per database policy files"
I think some more exposition here would be useful -- users may not know
what a policy provider is.  Maybe something like:
"Access control to Hive is currently defined by what Sentry calls policy
providers.  Sentry currently supports a file-based policy provider; see
below for an example.  A single global policy provider can be used to
control access to an entire HiveServer2 instance, or multiple dependent per
database policy providers can be linked to the global one."

>>> "Sentry provides authorization through a hook in HiveServer2"
I'm not a hive expert -- will all hive users know what a "hook" is?  Maybe
you should define this as well.

>>> "HadoopGroup mapping, which uses the underlying hadoop groups"
Going from the picture, it's actually more complicated -- right?  It will
either use Shell groups or LDAP groups.  Maybe a link here with some
explanation:
http://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-hdfs/HdfsPermissionsGuide.html#Group_Mapping

>>> "Next, lets look at how Sentry fits into the security landscape of
Hive."
I think this should be its own paragraph since it's only transition;
doesn't really have anything to do with the previous paragraph.
