Review comment:
that seems to me premature optimization which may just hit back
later...it would be simpler to run everything related to location thru the
translator and even move the handling of `CREATE_TABLE_AS_EXTERNAL` to there -
so that everything is on the same page.

> Under legacy table creation mode (hive.create.as.external.legacy=true), when
> a database has been created in a specific LOCATION, in a session where that
> database is Used, tables are created using the following command:
> {code:java}
> CREATE TABLE <tablename> AS SELECT <select statement>{code}
> should inherit the HDFS path from the database's location. Instead, Hive is
> trying to write the table data into
> /warehouse/tablespace/managed/hive/<database_directory_name>/<table_name>
> +Design+:
> In the CTAS query, first data is written in the target directory (which
> happens in HS2) and then the table is created(This happens in HMS). So here
> two decisions are being made i) target directory location ii) how the table
> should be created (table type, sd e.t.c).
> When HS2 needs a target location that needs to be set, it'll make create
> table dry run call to HMS (where table translation happens) and i) and ii)
> decisions are made within HMS and returns table object. Then HS2 will use
> this location set by HMS for placing the data.
