> Spark failes to load tables that have a keyword as column names
> Sample error:
> {code}
> org.apache.spark.SparkException: Job aborted due to stage failure: Task 0 in stage 157.0 failed 1 times, most recent failure: Lost task 0.0 in stage 157.0 (TID 4322, localhost): com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'key,value FROM [XXXXXX]'
> {code}
> A correct query would have been
> {code}
> SELECT `key`.`value` FROM ....
> {code}
