Hi, I changed my application to use Joda time instead of java.util.Date and I started getting this:
WARN ExternalAppendOnlyMap: Spilling in-memory map of 484 MB to disk (1 time so far) What does this mean? How can I fix this? Due to this a small job takes forever. Mohit. P.S.: I am using kyro serialization, have played around with several values of sparkRddMemFraction
