Hi, I have created a map by reading a text file val keyValueMap = file_read.map(t => t.getString(0) -> t.getString(4)).collect().toMap
Now I have another dataframe where I need to dynamically replace all the keys of Map with values val df_input = reading the file as dataframe val df_replacekeys = df_input.withColumn("map_values",lit(keyValueMap (col("key")))) Would really appreciate the help . Thanks, Divya
