Hi,
I am also facing the same problem. Has any one found out the solution yet?
It just returns a vague set of characters.
Please help..

Hi,
We've got the same problem here (randomly happens) :

Hi, all
Yes, it's a name of Wikipedia article. I am running WikipediaPageRank
example of Spark Bagels.
I am wondering whether there is any relation to buffer size of Kyro.
The page rank can be successfully finished, sometimes not because this kind
of Kyro exception happens too many times, which b
Not sure if this helps, but it does seem to be part of a name in a
Wikipedia article, and Wikipedia is the data set. So something is
reading this class name from the data.

Seems like there is some sort of stream corruption, causing Kryo read to
read a weird class name from the stream (the name "arl Fridtjof Rode" in
the exception cannot be a class!).
Not sure how to debug this.
@Patrick: Any idea?

I am not sure. Not every task will fail at this Kyro exception. In most
time, the cluster could successfully finish the WikipediaPageRank.
How could I debug this exception?
Thanks

Thanks for your reply. The SparkContext is configured as below:
sparkConf.setAppName("WikipediaPageRank")
sparkConf.set("spark.serializer",
"org.apache.spark.serializer.KryoSerializer")
sparkConf.set("spark.kryo.registrator", classOf[PRKryoRegistrator].getName)
val inputFile = args(0
Are you using classes from external libraries that have not been added to
the sparkContext, using sparkcontext.addJar()?
