Issue Type: Bug
Components: Documentation
Reporter: Ruslan Dautkhanov
>From Hive documentation -
{panel:title=Hive documentation}
Table names and column names are case insensitive.
* In Hive 0.12 and earlier, only alphanumeric and underscore characters are
allowed in table and column names.

[https://cwiki.apache.org/confluence/display/hive/languagemanual+select]
metastore.support.special.characters.tablename=true
makes possible to use special characters in table names.

If special characters are officially supported in Hive, I will be happy to
update the wiki or send a PR to fix this omission. Thanks!
