----------------------------------------
[~yetsun] Good. Do you use the same notebook?
Spark guys above said that this NoSuchElementException shouldn't be happening.
So while this looks like issue in sparkNB it might be something not good in
spark as well. Exception from BlockInfoManager is not expected way how missing
class definition (or similar) issue should manifest itself.
