cache function is not working on RDD from parallelize

[Edwin <al...@yahoo.com>]

Hi,
On a 5 node cluster, say I have data on the driver application node,
and then I call parallelize on the data, I get a rdd back. 
However, when I call cache on the rdd the rdd won't be cached (I checked
that through timing on count the realized-cached rdd, take as long as before
it was realized). So does anyone have any idea on this?
Thanks
Edwin
