Subject Re: SQLContext load. Filtering files
Date Thu, 27 Aug 2015 10:51:35 GMT
Thanks Akhil, I will have a look.

I have a dude regarding to spark streaming and filestream. If spark
streaming crashs and while spark was down new files are created in input
folder, when spark streaming is launched again, how can I process these
files?

Thanks.
Regards.
Miguel.
