Brock Noland commented on HIVE-7858:
------------------------------------
Hi,
This change doesn't really have anything to do with internal or external
tables. Parquet stores the compression algo used in the footer as such it's
possible to have a mix of snappy, gzip, etc compression types within the same
table. This change was to allow users to say "when I insert overwrite this
table, I want to use compression format x". Before this change they could only
use the global setting at a session or hive-site.xml level.
> Parquet compression should be configurable via table property

> ORC supports the orc.compress table property:
> https://cwiki.apache.org/confluence/display/Hive/LanguageManual+ORC
> {noformat}
> create table Addresses (
> name string,
> street string,
> city string,
> state string,
> zip int
> ) stored as orc tblproperties ("orc.compress"="NONE");
> {noformat}
> I think it'd be great to support the same for Parquet.
