val fs3File=sc.textFile("s3n://my bucket/myfolder/") fs3File.count do you suggest I should use sc.parallelize? many thanks From: Robert Collich [mailto:rcoll...@gmail.com] Sent: Monday, February 01, 2016 6:54 PM To: Lin, Hao; user Subject: Re: try to read multiple bz2 files in s3 Hi Hao, Could you please post the corresponding code?
