Hi All
I found some spark version(spark 1.4) return upper case aggregated column, and some return low case.
As below code,
df.groupby(col("...")).agg(count("number"))
may return
COUNT(number) ------ spark 1,4
count(number) ----- spark 1.6
Anyone know if there is configure parameter for this, or which PR change this?
Thank you very much.
Yu Wenpei.
