    Could you please give me the context for this change? Looks like only the test code is
using it for now. Thanks

    The last column name "DESC" is a bit ambiguious. It is also a reserved keyword in Oracle
(and perhaps others too).
    Can you change it to something a bit more descriptive. perhaps "DESCRIPTION" or "COMMENT"
if it fits your needs. COMMENT is used by some other tables in HMS schema as well. So would
be consistent as well (if it works for you that is)

    The new schema table is entirely detached from the rest of the tables, aka no FK references.
I am sure this is by design and me lacking the entire context.

    nit: Could you move this to be just below the last current "CREATE TABLE" statement but
before the first "CREATE INDEX"? It just implies a certain order, thats all.

    nit: I am guessing you had to insert quotes around "DESC" because it being a reserved
word. This makes the definition inconsistent with other columns in this table that do not
have the surrounding "". Changing the column name as suggested above should solve this as
well.

    nit: Can you move this "create table" to be just under the last current "create table"
?

Lines 6 (patched)
<https://reviews.apache.org/r/58994/#comment247025>

    nit: same as above



metastore/scripts/upgrade/oracle/hive-schema-3.0.0.oracle.sql
Lines 802 (patched)
<https://reviews.apache.org/r/58994/#comment247026>

    nit: same as above where the create table needs to be under the last current "create table"



metastore/scripts/upgrade/postgres/040-HIVE-16556.postgres.sql
Lines 6 (patched)
<https://reviews.apache.org/r/58994/#comment247027>

    nit: same as above

Lines 609 (patched)
<https://reviews.apache.org/r/58994/#comment247028>

    nit: same as above with ordering in the file.
