SparkR does not include SparkContext

[Siegfried Bilstein]

Hi,

I'm starting R on Spark via the sparkR script but I can't access the
sparkcontext as described in the programming guide. Any ideas?

Thanks,

Deleting HDFS files from Pyspark

[Siegfried Bilstein]

I've seen plenty of examples for creating HDFS files from pyspark but
haven't been able to figure out how to delete files from pyspark. Is there
an API I am missing for filesystem management? Or should I be including the
HDFS python modules?

Thanks,
Siegfried
