The method `corr` should live under `df.stat`: {code} df.stat.corr(col1, col2, method="pearson"): Double {code} `method` will be used when we add other correlations. Similar to SPARK-7240, UDAF will be added later. was: This JIRA is for computing the Pearson linear correlation for two numerical columns in a DataFrame.
