Huaxin Gao commented on SPARK-11977:
------------------------------------
I would like to work on this jira.
If the column name contains "." and hasn't been wrapped with backticks yet, I
will wrap it with backticks. Wenchen Fan and Reynold Xin, is this what you want
the fix to be? Thanks!
> Support accessing a DataFrame column using its name without backticks if the
