> Recently, https://issues.apache.org/jira/browse/HIVE-27665 was pushed on Hive. This will allow HMS to handle columns that are surrounded by backticks in filters.  An example of a customer who hit this problem had a filter in Spark like this:
> where date='2015-01-06'
> This didn't work because the word "date" is a keyword.  In order for the customer to work, the where clause should be changed to this:
> where `date`='2015-01-06'
> Spark strips out the backticks before passing the filter to HMS.  We need to no longer strip the backticks as a configurable flag.
