Carl Steinbach commented on HIVE-1977:
--------------------------------------
bq. 3. $describe column;
This doesn't make sense since tables in the same schema are allowed to have
columns with the same name. The correct syntax for describing a column is:
DESCRIBE table column
or
DESCRIBE db.table column
> DESCRIBE TABLE syntax doesn't support specifying a database qualified table
> name

> The syntax for DESCRIBE is broken. It should be:
> {code}
> DESCRIBE [EXTENDED] [database DOT]table [column]
> {code}
> but is actually
> {code}
> DESCRIBE [EXTENDED] table[DOT col_name]
> {code}
