Impala really has not delivered on the complex types that hive has (after

Dr Mitch,
My two cents here.
I don't have direct experience of Impala but in my humble opinion I share your
views that Hive provides the best metastore of all Big Data systems. Looking
around almost every product in one form and shape use Hive code somewhere. My

Nope, it shouldn't, because of Tez sessions the conf param is not job.

Hi,
A release was made for fix an authorization issue in Hive wherein parent
tables of partitions are not authenticated against for some partition-level
operations which was released on January 28 2016.
In the release notes, it was mentioned, this fix was released to all
branches.

We are allowing users to write/use their own UDF in our Hive environment.When
they create the function against the db, then all the users that can use the db
