I am trying to convert my RDD into Dataframe in pyspark.
My RDD:
[(['abc', '1,2'], 0), (['def', '4,6,7'], 1)]
I want the RDD in the form of a Dataframe:
Index Name Number
0 abc [1,2]
1 def [4,6,7]
I tried:
rd2=rd.map(lambda x,y: (y, x[0] , x[1]) ).toDF(["Index", "Name" , "Number"])
But I am getting errors
An error occurred while calling
z:org.apache.spark.api.python.PythonRDD.runJob.
: org.apache.spark.SparkException: Job aborted due to stage failure:
Task 0 in stage 62.0 failed 1 times, most recent failure: Lost task 0.0
in stage 62.0 (TID 88, localhost, executor driver):
org.apache.spark.api.python.PythonException: Traceback (most recent
call last):
Can you let me know, where am I going wrong?
Update:
rd2=rd.map(lambda x: (x[1], x[0][0] , x[0][1]))
I have the RDD in the form :
[(0, 'abc', '1,2'), (1, 'def', '4,6,7')]
To convert to Dataframe:
rd2.toDF(["Index", "Name" , "Number"])
Its still giving me error:
An error occurred while calling o2271.showString.

RDD.map
takes an unary function:so you cannot pass binary one.
If you want to split array:
