Subject Re: Issue with repartition and cache
Date Wed, 21 Jan 2015 18:37:54 GMT
Hi Dirceu,

Does the issue not show up if you run "map(f =>
f(1).asInstanceOf[Int]).sum" on the "train" RDD?  It appears that f(1) is
an String, not an Int.  If you're looking to parse and convert it, "toInt"
should be used instead of "asInstanceOf".

-Sandy
