> There is a small mistake in the patch of issue HIVE-2906. See the change of FromClauseParser.g
> -    : tabname=tableName (ts=tableSample)? (KW_AS? alias=identifier)?
> -    -> ^(TOK_TABREF $tabname $ts? $alias?)
> +    : tabname=tableName (props=tableProperties)? (ts=tableSample)? (KW_AS? alias=Identifier)?
> +    -> ^(TOK_TABREF $tabname $props? $ts? $alias?)
> With the 'identifier' changed to 'Identifier' we can not use nonReserved keywords as table alias.
