Description:
Since we don't allow users to query column names with dot in the middle such as
emp.no, don't allow users to create tables with such columns that cannot be
queried. Fix the documentation to reflect this fix.
Here is an example. Consider this table:
{code}
CREATE TABLE a (`emp.no` string);
select `emp.no` from a; fails with this message:
FAILED: RuntimeException java.lang.RuntimeException: cannot find field emp from
[0:emp.no]
{code}
The hive documentation needs to be fixed:
{code}
(https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DDL) seems to
indicate that any Unicode character can go between the backticks in the select
statement, but it doesn’t like the dot/colon or even select * when there is a
column that has a dot/colon.
