Yeah, saveAsTextFile is an RDD specific method. If you really want to use that
method, just turn the map into an RDD:
`sc.parallelize(x.toSeq).saveAsTextFile(...)`
Reading through the api-docs will present you many more alternate solutions!
Best,

Subject: Re: OutofMemoryError when generating output
Hi,
Thanks for the response. I tried to use countByKey. But I am not able to
write the output to console or to a file. Neither collect() nor
saveAsTextFile() work for the Map object that is generated after
countByKey().
val x = sc.textFile(baseFile)).map { line =>
val fields = line.split("\t")
(fields(11), fields(6)) // extract (month, user_id)
}.distinct().countByKey()
x.saveAsTextFile(...) // does not work. generates an error that
saveAstextFile is not defined for Map object
Is there a way to convert the Map object to an object that I can output to
console and to a file?
thanks
