I am using sklearn library for some regression for each group of data what i have.

def func(keys, values):
 clf = linear_model.LinearRegression()
 continued

rdd =df.rdd.map(lambda r :(Row(key1= r.key1, key2= r.key2), r))
           .groupByKey()\
           .flatMap(lambda kv: func(kv[0],kv[1]))

After the few minutes of execution i am getting below message, can any one help me to understand this?.

Seems like you are trying to connect via HTTPS to HTTP port or vice versa as per Jetty-9 warning: badMessage: 400 Illegal character
