calculate correlation between multiple columns and one specific column after groupby the spark data frame

Hi all, I am stuck at a correlation calculation problem. I have a dataframe like below:groupiddatacol1datacol2datacol3datacol*corr_co112345123465242175289325371235335315I want to calculate the correlation between all datacol columns and corr_col column by each
