@cloud-fan Thank you Wenchen for your comments. In my understanding , users
need to use back-tick to quote the column names if they wanted them to be
treated as a column name as opposed to column path. I tried the following
example
val df = Seq((1, 2, 3)).toDF("a_b", "a.c", "b.c")
df.select("a.c") => fails to resolve
df.select("`a.c`") => works fine.
Is this not how it is supposed to work ? Can you please elaborate by taking
a small
example ? Thanks in advance.
