Description

select `user` from team;

If we have a table `team`, and one of its column has been masked out with `****` with column level authorization. The above query will fail with error "SemanticException org.apache.hadoop.hive.ql.parse.ParseException: line 1:9 Failed to recognize predicate 'user'. Failed rule: 'identifier' in expression specification"

The root cause is that after re-written the ast, the back quote has been lost.
