[Wang, Daoyuan]

Hi Tobias,

Can you provide how you create the JsonRDD?

Thanks,
Daoyuan

Hi again,

So the reason that the error is showing up now is that suddenly data from a 
different dataset is showing up in my test dataset... don't ask me... anyway, 
this different dataset contains data like

  {"Click":"nonclicked", "Impression":1,
   "DisplayURL":4401798909506983219, "AdId":21215341, ...}
  {"Click":"nonclicked", "Impression":1,
   "DisplayURL":14452800566866169008, "AdId":10587781, ...}

and the DisplayURL seems to be too long for Long, while it is still inferred as 
a Long column.

So, what to do about this? Is jsonRDD inherently incapable of handling those 
long numbers or is it just an issue in the schema inference and I should file a 
JIRA issue?

Thanks
Tobias
