You can try to manipulate the string you want to output before saveAsTextFile,
something like
modify. flatMap(x=>x).map{x=>
val s=x.toString
s.subSequence(1,s.length-1)
}
Should have more optimized way.

Subject: Request for help in writing to Textfile
Hi Guys,
I am currently playing with huge data.I have an RDD which returns
RDD[List[(tuples)]].I need only the tuples to be written to textfile output
using saveAsTextFile function.
example:val mod=modify.saveASTextFile() returns ----
List((20140813,4,141127,3,HYPHLJLU,HY,KNGHWEB,USD,144.00,662.40,KY1),
(20140813,4,141127,3,HYPHLJLU,HY,DBLHWEB,USD,144.00,662.40,KY1))
List((20140813,4,141127,3,HYPHLJLU,HY,KNGHWEB,USD,144.00,662.40,KY1),
(20140813,4,141127,3,HYPHLJLU,HY,DBLHWEB,USD,144.00,662.40,KY1)
I need following output with only tuple values in a textfile.
20140813,4,141127,3,HYPHLJLU,HY,KNGHWEB,USD,144.00,662.40,KY1
20140813,4,141127,3,HYPHLJLU,HY,DBLHWEB,USD,144.00,662.40,KY1
